How should I track Beef Kidney, simmered?
Beef Kidney, simmered is high in iron. The simplest way to track Beef Kidney, simmered accurately is to weigh it raw, before cooking. According to USDA cooking yield data, meat loses 20–30% of its weight during cooking as moisture evaporates — so 150 g raw becomes roughly 105–120 g cooked. If you log the cooked weight using raw nutrition values, you will undercount your protein and calories. A kitchen scale takes the guesswork out of it. Quick tip: cook a batch, weigh it before and after, and you will know your personal shrink ratio for next time.
