How it works
Substitute amount = original amount × substitution ratioFrequently Asked Questions
How much applesauce replaces oil in a recipe?
A common 1:1 ratio works for most baked goods: 1 cup of oil can be replaced with 1 cup of unsweetened applesauce, though the result will be denser and slightly less rich — many bakers substitute only half the oil for better texture.
How do I make a buttermilk substitute?
Add 1 tablespoon of lemon juice or white vinegar per cup of regular milk, let sit 5–10 minutes to curdle slightly. This calculator scales that ratio to any amount of buttermilk your recipe needs.
Are substitution ratios always exactly 1:1?
No — some common ones aren't: 1 cup of butter substitutes for about ¾ cup of oil (butter contains water fat doesn't), and baking powder-to-baking soda substitutions use different ratios (3:1) since baking soda is far more potent. Always check the specific substitution you're using.
