Baking Powder Substitutions

Flavor: Cream of tartar has a mild tangy taste, so if you're making something delicate (like sugar cookies or shortbread), you might notice a tiny bit of extra sharpness. Most of the time, though, the flavor change is barely noticeable.

Texture: Your baked goods might turn out a little lighter and airier than usual. The cornstarch helps keep things balanced, but depending on the recipe, you might notice a slight difference—maybe a bit crispier or drier.
