What is the shelf life of buttermilk batter?

The shelf life of buttermilk batter is typically considered to be around 2 days. This time frame is based on the understanding that buttermilk itself contains lactic acid bacteria, which can promote fermentation and souring if left too long, potentially compromising the quality and safety of the batter. After 2 days, the taste and texture may begin to deteriorate, making it less ideal for use in recipes. Keeping the batter refrigerated can help extend its usability, but it's recommended to use it within this duration to ensure the best results in cooking or baking. Understanding this helps in proper inventory management and food safety practices in a back-of-house environment.
