Frequently Asked Questions

Can I substitute buttermilk with regular milk?

For baking, mix 1 cup milk with 1 tablespoon lemon juice or vinegar, let stand 5 minutes. This won't have live cultures but provides the acidity baking needs.

Why does buttermilk make baking better?

Buttermilk's acidity reacts with baking soda to create lift, tenderizes gluten for softer texture, and adds tangy flavor. It's the secret to fluffy pancakes and tender biscuits.

Is buttermilk just spoiled milk?

No, buttermilk is intentionally cultured with specific bacteria that create a safe, tangy product. Spoiled milk has harmful bacteria and is unsafe to consume.
