So I make a pot of chili or stew. myFitnessPal allows me to create a recipe but it wants the serving size. So I guess not real accurate or I could empty the pot and use a measuring cup...not conveinet....so is there a method using the recipe and have it determine the calories etc. by cups? So given the recipe, can it calculate the total size of the pot of whatever and say the pot has this many cups at this nutrition value?
