Green pea flour is one of the latest options in the burgeoning gluten-free flour category. It can add an earthy element and a splash of colour to pancakes, cookies, and savoury muffins. If you can’t find the flour at a store near you, try making your own by blending dried split green peas into a very fine powder in a food processor, spice grinder, or high-powered blender. These muffins are best served warm with a wisp of butter.
