How do you determine the number of calories when part of the recipe doesn't get eaten? For instance, you marinate a piece of meat. Obviously when you take it out of the marinade what is left are ingredients that don't get eaten, so to calculate nutrition on every single ingredient in a recipe would be misleading.
I made a pork roast tonight, just pork and onions with some water, sugar and other things mixed together poured over it. (It was delicious.) The only thing that actually gets eaten is the pork..ok and the onions because I will eat cooked onions by the plateful if they are yummy. So I don't know how to account for the sugar, soy sauce, vinegar, etc. in the recipe when only a portion of it would have soaked into the meat.
