Frequently Asked Questions
Do spices and leaveners scale linearly?
When scaling recipes up significantly (more than 4x), consider increasing spices, herbs, and baking powder slightly more conservatively than linear multiplication.
Does cooking time change when doubling a recipe?
Cooking time usually stays the same if you use two pans in the oven, but increases if you use one larger, deeper dish.
