I recently started making my own kefir (easier than making yogurt!) and regularly sub it in recipes calling for buttermilk, yogurt and even sour cream sometimes. I find I actually like kefir better than plain yogurt. But I’m wondering if there are any recipes that take advantage of the effervescence it can develop in a tightly-closed container.

And really I’m looking for any recipes that call for kefir in particular — subbing it for the other ingredients is handy and tastes great but surely, since it’s been around for so long, there are recipes that specify it. Cheeses? Breads? Who knows what else…
