english: For instance, when we bake a fluffy sponge cake, even though the resulting delicious treat is much bigger in size than the cake batter that went into the oven, the weight of the cake batter should still equal the weight of the cake plus the moisture that has evaporated.
non_english: Recimo, ko spečemo rahel biskvit, je okusen pečeni posladek veliko večji od testa, ki smo ga dali v pečico, a teža testa bi morala ostati enaka teži peciva, če dodamo izparelo vlago.
