Load Saved Recipes
Analyze and Save Recipes
Add Items From Label
Food Log Reports
Welcome to ANALYZE MY RECIPES!
This is a proof of concept site. The real work and power reside in the algorithms being developed to analyze food and recipes in real time.
If you are an experienced developer who cooks and has an interest in human nutrition:
See development log/comments below. I add comments periodically, if not routinely.
If you would like to talk tech, just ping me.

Added a report tab for logged food. One must log in for this to enable.
Pie chart displays percentage energy from each energy source, plus calories.
Stacked bar chart displays daily consumption over time.
Options for today only, end time series on today, skip days under a threshold, and start and end dates.
Options auto-save to preferances and are in effect on subsequent visits.
Added an admin tab, just for me.

Fixed some annoying bugs in the diet logger (I am using it to lose weight).
Sunday, January 12, 2014:
I have decided to keep this sandbox active for a few more months in order to:
Implement an HTTP web service using ASP.NET Web API and Json
Start re-implementing functionality for GeeksWhoCook using MVC
Implement reasonable authentication/authorization
Open the API to those who might find it useful, especially cooking apps on mobile devices
Bottom line, this looks like fun.
Sunday, January 5, 2014:
location path="." inheritInChildApplications="false"
tags to accommodate downstream sites.
Implemented an instance of blogengine.net to experiment with. It may still be running at
Redid the table SQL scripts for all the data bases to preserve structure, keys, constraints and indexes.
If a fog person reads this, ping me. It would be interesting.
Sunday, December 29, 2013:
We celebrate the birth of Kahless, on this most Klingon Khristmas! Qapla'!
The nutrition label now has information decoupled from flow on extended nutrition information.
I added Vitamin D. About time!
The extended nutrition label can optionally skip any N/A values, and auto size.
Duplicates from USDA databases are removed. Specifically, CN has many duplicated from SR.
All things being equal, food searches sort with most complete data nutrition information first.
Created admin routines to regenerate the search cache. Useful for deprecations and updates.
Worked on admin routines used to update databases and references to databases as updates from outside occur.
Julia's associative memory is more specific. Duplicates with base references eliminated.
Search results are now cached. The second time a phrase is analyzed, the results can be retrieved directly.
The food logger now saves alias strings, to aid in admin functions and recovery.
Fixed a LINQ to SQL Optimistic Concurrency problem when deleting recipes in production.
Wednesday, November 27, 2013:
This site will NOT move to Azure after all!
I implemented a full copy of this site and its data in Azure.
I tested across free, shared, standard, and even 2-processor sized sites.
Azure was always slower by at least a factor of three, and often much, much more.
Often, identical back to back runs had significantly different times (all slower) for no reason.
Holy moly! Who would have thunk!
Sunday, November 24, 2013:
Many changes are coming!
This site will migrate by late January.
The new sites,
, will replace this development site.
These sites will emphasize cooking skills, weight loss and maintenance, and meeting others.
Hosting will migrate to
, with a test site extant later today.
All USDA databases (SR, CN, FNDDS) are now consolidated.
Various admin tools have been implemented to allow me to update USDA and other databases as regular updates of them are released.
Sunday, October 27, 2013:
has undergone some surgery.
Julia associative memory wipe/regenration implemented.
Administrator can now edit and resave any recipe.
Loaded recipes can be re-analyzed.
If they send back a Terminator from the future to shut down SkeyChef and Julia...
... it will look like Chef Ramsay.
Sunday, October 13, 2013:
Today is the day the artificial intelligence
has gone live.
This was the last major brain section for the food analysis AI.
This is the part that learns patterns from users who save and edit recipes.
The more people analyze and refine food choices, the smarter Julia gets at choosing her matches.
Queue the SkeyChef Terminator jokes...
Saturday, September 28, 2013:
Many new heuristic additions.
Nut Butter Dude, ping me if you see this....
Sunday, September 22, 2013:
Converted all varchar to nvarchar in databases.
Friday, September 13, 2013:
Recipe measurements now round to nearest 1/8, 1/4, or 1/3, in keeping with common kitchen measurements.
Number rounding and string conversion is now more regular.
Updated help info on analyzer tab.
Added item to "No Matches" message.
Fixed "Do NOT Copy Food Name" issues.
Wednesday, September 11, 2013:
Bug! Edge case!
When a database supplies a measure in grams with Amount greater than 1, the converter got crazy.
Amount and weight are now normalized around one in ParsePortionLoadedFromDatabase().
One pound of basmati rice no longer weighs 22680 grams!
Monday, August 12, 2013:
Noticed that micro-nutrient percentages were displaying incorrectly on the long label. Fixed.
Holy crap! I forgot to re-initilaize HA objects on some search list regeneration! Fixed!
Sunday, July 21, 2013:
Working on better structured exception handling.
Errors email directly to me.
Wednesday, July 17, 2013:
A bunch of clean-up entering food items from their nutrition labels.
Saturday, July 13, 2013:
Recipes and foods entered from labels can be deleted by their owners. (or me!)
Recipes or foods entered from labels are deleted smart: if referenced by a log or another recipe, they are deprecated, else they are removed.
Recipe analyzer matching lists are now ajaxified with search. Hoo ya!
Recipes can now "lock" user text. A food typed by a user can prevent the description from the backing database item from replacing that text.
As always, numerous bug and display fixes.
Sunday, June 30, 2013:
Food logger fixes. I had become too clever by half. Better now.
Food, recipe, label, and food logger databases tuned for performance (indexes added or fixed).
Various layout and bug fixes.
Sunday, June 16, 2013:
A lot of work on the recipe analyzer has been done.
Many errors corrected, two factor analyzer moved into the object, portions works as it should, etc.
A user brought to light problems, so I dove in all the way on the recipe analyzer.
Sunday, June 2, 2013:
Added favorites to food logger.
Still needs deletes and some debugging, but still kind of cool.
Tuesday, May 28, 2013:
Whoa! Food Label addition was screwed up.
Hopefully fixed now...
Sunday, May 26, 2013:
Lots of work cleaning up and robustifying Food Log.
Food Log may be ready for prime time!
Have begun cleaning up the overall de-modeling creep: Moving inappropriate functionality to model from controller and view.
Sunday, May 19, 2013:
Un-oops, sigh of relief. Primary keys were set incorrectly in the production database. Silly me.
OOOPS... Cannot add a new foodItem. Well, I'll be fixing... Odd, it works in the local test environment.
You may now log your food habits.
There may be bugs, but a LOT of work is finished!
WOO DAMN HOO!
Saturday, May 18, 2013:
More work on the food logger...
If the hot dog guy from the Farmers Market reads this, please email me.
I will be cooking some duck breasts tonight.
Sunday, May 12, 2013:
Login required for food logger.
Food logger persists selection across tab changes.
Other food logger controls persist states.
Login pops back to page you logged in from.
I will next finish entry of food log foodItems and their persistence.
Saturday, May 11, 2013:
More food logger work...
I have been to Yosemite. It was grand.
Monday, Thursday 28, 2013:
Fixed nasty little exception in recipe analyzer.
Playing with on demand combo box in food logger.
Monday, March 25, 2013:
Monkeyed around with food logger...
Sunday, March 3, 2013:
Improved drag and drop on the food logger.
Drag and drop on the food logger should now work as advertised.
Slow cooking two kinds of pork ribs this afternoon.
Saturday, February 23, 2013:
Resumed work on logging one's food consumption. See the "Food Log" tab.
AJAX-ified the nutrition label and data grid.
Wired up the nutrition label to the current meal in context.
Making a goat cheese, chard, and herb pie in a phyllo crust tonight.
Monday, February 18, 2013:
Added synonyms. This came as a result of "oe" plurals, like tomatoes and potatoes. Very gnarly.
BTW, Dan Quayle was treated unfairly over this.
Recipe analyzer now handles duplicates much better.
Recipe analyzer algorithm optimized. Only new foodItems are re-analyzed.
Better handling of updated recipe via the text box.
Better handling of updated recipe via the controls after an initial analysis.
Better resolutuion of contention when changes occur in both text and controls.
Better handling of wordy measures supplied by the databases.
Addition of a new RawRecipeCompare object, allowing fast and intelligent detection of differences between two text recipes.
Friday, January 25, 2013:
Added a ReaderWriterLock() to manage access to the treeview node map in BrowseFoods. This was needed because when a session adds a recipe or label, the first session to hit BrowseFoods performs an application wide update of the TreeNodes.
Thursday, January 24, 2013:
Happy Birthday to me! (Unlike Gandalf, I have not been on (middle) Earth for ~18,000 years.)
Fixed insidious timing/lock bug involving static initialization during the application start thread.
Fixed a number of little irregularities from my "C" level to do list:
Fixed RadTreeView to restore selection on return to browse food tab.
Made recipe and label treeview updates application global.
Moved buffered treeview structure creation to application start thread.
Sorted the recipe list.
Wednesday, January 16, 2013:
Adding new databases is now completely independedent of the NutritionDataCollection dll. A custom configuration section in web.config now registers a database and allows deprecation and visiblity.
This had been bugging me for a while, so kudos to me for finally fixing this once and for all!
Monday, January 14, 2013:
Excluded old databases from recipe analysis.
Turned search threading back on.
Saturday, January 12, 2013:
Added SR25 and CN16 updated USDA databases.
Updated FNDDS5 tomorrow...
Wednesday, January 9, 2013:
The managed environment launches multiple instances of the application. Modified rolling log file to be on a per instance basis to ease debugging.
Fixed centering issue on nutritition label (only appeared on mobile devices).
Cooking a goat cheese/bacon omelette from local ingredients tonight.
Sunday, January 6, 2013:
Leptonica and Tesseract successfully compiled and run. I need to scan nutrition labels from products on store shelves for use in lookups.
Work on an Apple iOS app to facilitate this site has begun.
Food Log begun.
Cooked a very nice pork loin roast with a pomegranate and balsamic glaze last night.
Sunday, October 7, 2012:
Fixed issues around duplicate derived measures for food foodItems.
Fixed issues around deleting measure from raw recipe box on Analyze Recipes screen.
Saturday, October 6, 2012:
I spent the past week in the mountains kayaking, hiking and programming.
The AI has been completely refactored into a HeuristicAnalyzer object.
The new AI object is 750% faster at analyzing a recipe than previous to today.
Very much work was done on the heuristics used to select recipe ingredient matches. Hit rate is HUGELY improved.
The way saved recipes are used as ingredients is fixed. Searches only against title.
T and t common measurement usage fixed.
Many, many proprietary additions to the heuristic analyzer.
Saturday, August 11, 2012:
I am writing this from the outer banks of North Carolina. Sweet!
There have been many, many deploys since my last notes here.
Yes, I know I broke the recipe analyzer and label entry. FIXED!
Newest Telerik controls deployed, licensed version.
Label entry may be complete. Testers still testing.
Next foodItems to implement:
Personal Food Log.
Look and Feel: Working with designer to move from a developer sandbox to a functioning public site.
Look and Feel: Enable site wide skinning with control overrides as needed.
Monday, June 25, 2012:

Wow! Still almost there!
Sunday, April 22, 2012:
Lot's more done!
Save and load recipes complete.
Label ready for extended micro-nutrient values.
Various bug fixes and optimizations, of course.
Next foodItems to implement:
Add foodItems to database from the nutrition label on a purchased foodItem.
Enable use of recipes and purchased foodItems in a recipe.
Add "Format Recipe" with directions, picture, cooking time, etc. and a "Print" function.
Add personal food log with reports.
Wow! Almost there!
Sunday, April 1, 2012:
Much has been done, though I have not been consistent updating these comments. Apologies for that.
Recipe save database is in place.
"Load Saved Recipes" tab is almost complete, but controls are not yet "wired" up. Take a look.
Telerik controls updated and re-integrated with the development environment.
Various bug fixes and optimizations.
Tuesday, January 24, 2012:
Today is my birthday.
So many fixes, refactors, and AI tuning, I will not describe today.
Saturday, January 7, 2012:
Added heuristics to sort and search algorithms. Food matching greatly improved.

Database and tables for recipe "Save" implemented.
Thursday, December 29, 2011:
ALL implementation specific dependencies removed from NutritionDataCollection dll in preparation for move to MVC3.
TreeView data intializer refactored (Browse food tab). LINQ queries optimized. 400% increase in performance!
Sunday, December 18, 2011:
LINQ optimizations on nutrition info query, as suggested by S.R. Nice catch!
Bug fixes to nutrition label adder. Fixes values in recipe analyzer tab.
Better maintenence of common measure on browse tab when changing foods.
Tuesday, December 13, 2011:
Build Recipes tab activated:
This will link with the anlayzer on the next tab.
Nutrition label to be included.
Formatted print to be implemented.
Keep checking, I am working....
Saturday, December 10, 2011:
Analyze Recipes portioning (slice, cookie, serving, etc.) and number of servings per recipe now works.
Wednesday, December 7, 2011:
Fixed default portion size to first non-derived portion.
Working on portioning in recipe analyzer...
Wednesday, December 7, 2011:
Working on portioning in recipe analyzer...
Sunday, Novenber 27, 2011:
The recipe anlayzer has been debugged and appears robust. Of course, testing will tell.
Analyzer threads off each line to a task.
Dynamic controls created and maintained against the "raw" recipe.
Scoring algorithm/AI continues to add heuristics.
Saturday, October 8, 2011:
I am back. A trip to France and a new contracting opportunity consumed time.
The full cut and paste recipe analyzer with AI ingredient analyzer is done in a thick client prototype. I will add this over the next several weeks.
The look and feel is being revised by a web designer here in NC. Stay tuned.
Conversion to WCF to expose service, operation and data contracts under way.
It's good to be back!
Sunday, July 17, 2011:
Paging now makes sure the top row is selected via PreRender and PageIndexChanged events, eliminating an exception.
The measure (oz, egg, piece, etc.) now resets properly when the selected food changes, eliminating an exception.
