I often create a recipe but then substitute ingredients later on when I make it again. Do I have to go back to the recipe and change it every time I make a substitution? It would be great if when it was added to your foods, you could see each ingredient when you clicked on the recipe in the diary page and change it in the diary page, rather than changing the recipe permanently. This would leave the original recipe as it is, and allow substitutions to be made when needed. If this isn't available I am suggesting this feature!
