Common baking substitutions, scaled

Both Texas A&M AgriLife Extension and Utah State University Extension publish the same core swaps. For each teaspoon of baking powder, use ¼ teaspoon baking soda plus ⅝ teaspoon cream of tartar. Utah State also lists ¼ teaspoon baking soda plus ½ cup soured milk or buttermilk. For 1 cup of buttermilk, use 1 tablespoon of vinegar or lemon juice plus enough milk to make 1 cup and let it stand 5 minutes, or use 1 cup of plain yogurt. For 1 cup of self-rising flour, use 1 cup all-purpose flour plus 1½ teaspoons baking powder and ¼ teaspoon salt. For 1 cup of sifted cake flour, use 1 cup of sifted all-purpose flour minus 2 tablespoons.

Worked example. A pancake recipe needs 2 cups of self-rising flour. Use 2 cups all-purpose flour, 3 teaspoons (1 tablespoon) baking powder and ½ teaspoon salt.

The swaps are the extension services' own numbers multiplied by your amount; nothing here is interpolated. Substitutes can change flavour, colour and texture slightly, as Utah State notes, so the result may not match the original exactly.

Scope

Substitutes may change taste, colour or texture. The extension charts are general guidance; the Utah State chart dates from 1992, so use judgement on modern flours and products.
