These tender fluffy masa harina biscuits are everything! They're kind of a cross between a classic biscuit and a corn muffin, and the perfect accompaniment to chilis, soups, and stews of all sorts.
Put the dry ingredients (flour, masa harina, baking powder, baking soda, and salt) in the bowl of the food processor and pulse to combine.
Add the cold butter, in pieces, to the machine.
Pulse in the cold butter, about 25 pulses, to combine and create a coarse crumbly mixture.
Slowly add in the buttermilk, while pulsing, until the dough comes together.
Turn the dough out onto a floured surface and bring the dough together, adding a little flour if it's too wet and to prevent sticking.
Pat or roll to about 1 inch thick and cut into biscuits. I used a 2 1/2 inch round biscuit cutter. You'll get about 10+ biscuits. Note: it helps to flour the edges of the biscuit cutter between cuts to prevent sticking.
Place them on parchment paper or a Silpat liner and bake at 425 for about 15 minutes. They don't get brown, so don't overcook waiting for them to take on color.
Serve hot out of the oven (my preference!) with butter or honey.
