Need to do this: 1) Write down about 15 of "my" recipes (ingredients and steps for each). 2) Each weekend, click on 4 or 5 of those recipes and make a list of ingredients to buy (some might already be there at home). Which would be the simplest phone or web app for this? I kind of know how to do this for recipes found on the internet. But how to do it efficiently for my own recipes? Any links or reco's most appreciated by me and my assistant cooks!
