There's always buttermilk in the fridge at our house. Mainly because I like to make buttermilk pancakes on Sundays. And even though I love pancakes, it's good to mix it up every once in a while. So I mixed up a batch of Rosa's Biscuits, recipe from the September 2014 issue of Bon Appetit magazine. Rosa is the pastry chef at Del Posto in New York. We ate these biscuits right out of the oven, just like it said in the story that goes with the recipe. These biscuits are so good they need nothing to make them better; no jam, no nutella, no almond butter. Nothing.
