The biscuits pictured have more cornmeal in them than the final recipe I created. So yours won't be as grainy, FYI. They will be more tender and fluffy than the ones pictured 👅 Look for fine ground cornmeal to make these biscuits. Other grinds will work, but I prefer finely ground for it's soft texture. I've never tried making biscuits gluten-free, but it surely can be done, I'm just not sure what the best method is for that.
