My wife and I got very into making smoothies a year or two ago when we got a nice blender.
We found many recipes online but then were finding it annoying trying to figure out which smoothie we could make that day depending on the ingredients we had.
SO! I made a very fun tool in Google Docs. You load in ingredients, load in recipes, and then on a tab you tell it what ingredients you have right now, and it tells you what you can make.
Try it below or clone it to try it for yourself here.
The doc works by looking at ingredients in each recipe doing a COUNTIF for each ingredient if it is present in your list of ingredients in hand. Then, if the total number of present ingredients for a recipe equals 100%, it shows up in your list of available recipes.
