One of the best ways to activate dough without using yeast is to use baking soda and acid. This method can be used for almost any type of dough, including pizza dough, breads, pancakes and more. To do this you will need a tablespoon of baking soda and an acidic ingredient such as buttermilk or yogurt in place of the yeast. Simply mix these two ingredients together in your bowl with some warm water until they are combined nicely before adding your dry ingredients like flour, salt, sugar etc. Mix it all together until smooth then let it sit for about 10 minutes so that the chemical reaction can take effect - this will cause your mixture to bubble up and create little pockets throughout which help give structure to your finished product when baked! The result is a delicious final product full of flavour without having used any yeast at all!
