Buttermilk

How to Choose the Best

Always check the expiration date of buttermilk before purchasing to make sure it is as fresh as possible.  Beyond that, local dairies in your community may offer buttermilk that will taste far superior to anything commercially produced and available in large grocery stores.

Shelf Life and Storage

Like most other dairy, buttermilk is best kept refrigerated to prevent spoilage. Buttermilk has a long shelf life because of its high acidity and is fine to use for approximately seven days past the sell-by date if stored properly.

Freezing

Buttermilk can be frozen for up to two months if the expiration date is approaching and it cannot be used in time. Defrosted buttermilk is best used for cooking or baking rather than for drinking.

Preparation Suggestions

Buttermilk can be used in baking items like biscuits and for sweeter recipes like pies and pancakes. The acidity and enzymes in buttermilk can help tenderize meat, making it a good marinade. It can also be used as milk substitute in certain applications.
