Cultured Buttermilk Measuring FAQs
Why does buttermilk produce exceptionally tender baked goods? ▾
Lactic acid weakens gluten networks and reacts vigorously with alkaline baking soda, generating carbon dioxide lift and a soft crumb.
Can you freeze leftover buttermilk for future baking? ▾
Yes, freeze in 1/2-cup portions or ice cube trays; thaw and whisk to blend before mixing into batters.
