Learn how to freeze buttermilk to extend its shelf-life and avoid wasting food. In this guide, I’ll show you how to freeze buttermilk, how long it lasts, and how to use it after defrosting.
Fill the ice cube trays/molds ¾ of the way full with buttermilk. (Leave room for expansion or else you’ll end up with a big mess!)
Once frozen solid, transfer the buttermilk cubes to a large ziploc bag.
Label the bag with the date and freeze for up to 3 months.
Defrosting
Transfer as many cubes as you need to a container and leave them to thaw in the refrigerator. Use within 1 to 2 days.
Or, just pop a few cubes in a saucepan on the stove or in the microwave. Heat in 30-second increments until thawed.
Notes
Each frozen cube = about ⅓ cup of buttermilk. This isn’t always accurate depending on the molds or ice cube trays you use. To be extra precise, pour the buttermilk into a measuring spoon or cup before pouring it into the molds.Note: The longer the buttermilk is frozen, the more ice crystals will form. This can cause it to separate, have a grainy texture, and form a thinner consistency when thawed.
