Buttermilk should be reserved for pancakes, which are incompatible with tuna.

You are correct about tuna and buttermilk. Everybody knows they are mortal enemies. I'll give you that one.

Buttermilk is best cold in a tumbler. Its so good when you drink it, it makes your eyes kind of roll back and go scrunchy. (A word I have never before in my life used. I promise not to use it again.)
