Pru at Perfecting Pru chose today’s project – potato gratin in a muffin tin. Did you try it? I made it and it worked but I thought it was a bit lacking in flavor. There’s no butter in this, other than the cooking spray on the tin (maybe I should have actually rubbed a stick of butter on it). Easy to make, but those muffin tins are a pain to clean if you don’t use liners, and this recipe didn’t. I can safely tell you, having cooked hundreds of muffin tin recipes, for my upcoming book The Muffin Tin Cookbook, that you want to use liners whenever possible!
