Baking Soda + Cream of Tartar (Best Option)
1/4 teaspoon baking soda + 1/2 teaspoon cream of tartar per 1 teaspoon baking powderBaking powder is a combination of baking soda (a base) and an acid, typically cream of tartar. Using baking soda with cream of tartar replicates this balance, producing carbon dioxide gas that helps aerate the pasta dough slightly, improving tenderness and texture.
Ensure accurate measurement to maintain the acid-base balance; too much baking soda can cause a soapy or metallic taste. Mix the two powders thoroughly before incorporating into the dough.
Compared to commercial baking powder, this substitute offers the same leavening effect and texture, preserving the pasta's characteristic bite and lightness without introducing unwanted flavors.
