How to scale a recipe
Divide the servings you want by the servings in the recipe. That number is the scaling factor. Going from 4 to 10 servings is a factor of 2.5, so 2 cups of flour become 5 cups and 3/4 cup of milk becomes 1 7/8 cups.
Tips for good results
- Baking: weigh flour and sugar when you scale more than 2×; cups get less accurate.
- Eggs: round to the nearest whole egg, or beat one and use part of it.
- Salt and spices: start with a little less than the scaled amount and adjust to taste.
- Pans and time: a bigger batch may need a bigger pan or two pans, and the baking time changes.
