weights

unknown

I was wondering..do foods weigh different after they've been heated. I pull things out of the fridge and weigh, then heat and eat. Is it heavier after you weigh it, or less? this is nitpicky and perhaps a silly question.
which one should you use?

Always use a weight prior to cooking - what happens to it after cooking is really immaterial unless you introduce more ingredients (not spices) into the food. Cooking will remove components like water - which can make the food weight less. Take into account all ingredients when you cook it, including oil, prior to cooking.
