This fermented dairy product is essentially milk soured with lactic acid which is a by-product of cultured bacteria feasting on lactose. It gives richness and tanginess to many types of quickbreads and cakes, including muffins, which is the first thing I decided to bake. My favourite muffin recipe from school is a bran, pumpkin and ginger muffin, moist and light with an interesting crunch from toasted millet. Even though Eric has an irrational hatred of pumpkin due to a traumatic rotting pumpkin science experiment in elementary school, he admitted that this muffin was very good.

Next, the obvious destination for buttermilk is in buttermilk biscuits, a perfect accompaniment to a hearty beef stew which was on the menu for dinner. From Dorie Greenspan's Baking: From My Home to Yours, I found a simple recipe which made the perfect buttery oven-fresh sponge for the rich gravy.

Finally, the buttermilk found its way into a Devil's Food cake which I soaked with Bailey's irish cream syrup and layered with coffee buttercream. In case you think we eat like this every night, you are mistaken. Having a house guest and leftover buttermilk certainly motivates me to cook more than just on Sundays! The only problem is that I still have about 1 cup of buttermilk left but no longer any recipe ideas nor any space in my belly. Maybe pancakes on Saturday?
