Questions

How are the numbers calculated?
Equal boxes: weight per box = batch weight ÷ boxes, calories per box = batch calories ÷ boxes. Custom portion: calories = batch calories × portion weight ÷ batch weight. 450 g of a 1,800 g batch of 2,400 kcal is 600 kcal, and 1,350 g remain.
Where do the calories come from?
Only from you: add up the labels of your ingredients. The tool has no food database and does not look anything up.
Is the result accurate?
It assumes the dish is mixed evenly, so every gram carries the same calories. A portion with more meat than sauce will differ. It is a kitchen helper, not medical or dietary advice.
Does it count the weight of the container?
No. Weigh the cooked food without the pot, or subtract the empty pot from the batch weight before you type it.
