Frequently asked questions
Can I double any recipe by doubling every ingredient?
Mostly, but cooking time, pan size, salt and strong spices may need adjusting. Baking recipes are the most sensitive to changes.
Which amounts should I not scale exactly?
Salt, spices, leavening and baking time often do not scale in a straight line. Scale them, then taste and adjust, and check pan size too.
How should I format the ingredients?
Put one ingredient per line with the amount first, such as 2 cups flour. Fractions like 1/2 work, and clear amounts give the best result.
