When making buttermilk can you use limes instead of lemons?

Yes, you can use limes instead of lemons to make buttermilk. Both limes and lemons provide the acidity needed to curdle milk, resulting in a similar tangy flavor. Simply mix 1 tablespoon of lime juice with 1 cup of milk, let it sit for about 5-10 minutes, and it will thicken and sour just like traditional buttermilk.
