Frequently asked questions

Does scaling work for baking soda and spices?

Leavening agents and strong spices don't always scale linearly — start with slightly less than the linear amount for large batches.

What about cook time?

Cook time doesn't scale the same way as ingredients; larger batches often need more time, not proportionally more.
