FAQ’s

What does discard mean in sourdough?

Discard is simply sourdough starter that is no longer at its peak. It may be leftover starter from a recipe or if you simply have excess starter that isn’t active enough to bake bread with, it would be considered discard.

Why do my oatmeal cookies taste dry?

If your oatmeal cookies are dry you likely added too much flour. Try adding less flour next time. Decrease flour by 1/4 cup until you achieve a typical cookie dough consistency.

Do you have to use baking soda to make oatmeal cookies?

You don’t. If you don’t have baking soda you can substitute for baking powder instead. Baking soda is much stronger than baking powder so when using baking powder instead, use 3 times the amount of baking soda recommended.

In conclusion, sourdough oatmeal cookies are a unique and delicious twist on a classic treat. The tangy flavor of the sourdough starter adds depth and complexity to the sweetness of the cookie, creating a perfectly balanced dessert. These cookies are not only tasty but also offer potential health benefits from the fermentation process of the sourdough starter. Whether you are a seasoned baker or just looking to try something new in the kitchen, sourdough oatmeal cookies are sure to become a favorite in your kitchen.
