I would normally tell you to keep this recipe on hand for the next time you have leftover sweet potatoes. But really, these biscuits were so good that I think you should cook a sweet potato right now to have one ready. I followed the recipe as written, although I skipped the final brush of butter. Oh, and I didn’t make cute circles, although I will try that next time. The Southern cooks may be laughing right now, but I’ve only made real biscuits from scratch a few times, so I am still on the steep part of the learning curve.
