The following Everyday Savings Tip comes from, Rhonda:
I buy buttermilk when it is marked down for clearance at the grocery store because it is nearing its expiration date – usually for $.39 per half gallon. When I get it home I freeze it in cubes in ice trays. The trays I have hold about 2 TBS for each cube. I empty the trays into a zip to freezer bag and date each bag to make sure I use the oldest ones first. I also sometimes will freeze a pint or a quart at a time in the original container.
We make a lot of buttermilk cornbread and biscuits. This way I always have buttermilk for my southern recipes, even in small quantities. Plus it saves me about $6 a month in milk purchases. The best part is I never throw out spoiled buttermilk…not that buttermilk isn’t already “spoiled” to some degree anyway!
