Kitchen tip: If you prefer pecans to almonds, pulse flour, 1/2 cup pecans, baking powder, baking soda and salt in a food processor until fine crumbs form. Store almond flour (and all nuts) in the freezer to prevent the natural oils from going rancid.
Kitchen tip: To make buttermilk, stir 3/4 cup milk with 2 1/2 tsp white vinegar and let stand for 10 min before using.
