Nutrition Tips
- Use buttermilk as a marinade for chicken to tenderize the meat naturally with its lactic acid.
- Substitute regular milk with buttermilk in baking for a fluffier, more tender crumb in cakes and pancakes.
- Check the label for added sodium, as some commercial brands use salt as a preservative.
- Shake the container well before pouring, as the solids can settle at the bottom over time.
- Store buttermilk in the coldest part of your refrigerator to maintain the activity of the beneficial probiotics.

Frequently Asked Questions
Is buttermilk high in fat?+
Despite its name, most commercial buttermilk is actually low-fat or fat-free. It is traditionally the liquid left over after churning butter from cream, though modern versions are cultured low-fat milk.
Can people with lactose intolerance drink buttermilk?+
Many people with mild lactose intolerance find buttermilk easier to digest than regular milk. The fermentation process converts some of the lactose into lactic acid, reducing the overall lactose content.
How does buttermilk affect baking?+
The acid in buttermilk reacts with baking soda to create carbon dioxide bubbles. This chemical reaction acts as a leavening agent, helping baked goods rise and creating a tender texture.
