How to Freeze Buttermilk

By Yvette Sajem

Although buttermilk has a comparatively long refrigerator shelf life, you can extend that by freezing it. With its tart flavor and creamy texture, buttermilk lends a velvety richness to cakes, pies, cookies, fudge, mashed potatoes, biscuits and pancakes. But most recipes only need a small quantity of buttermilk. To make the most of a container of buttermilk, freeze the entire container or package it into smaller servings that work for your recipes.
