Please play with this recipe. Add and subtract to your heart’s content. No rye flour in the pantry? Substitute another flour, like whole-wheat, buckwheat, or, if you must, more all-purpose flour. Black pepper is not my thing, but you may love it. Goat cheese? Why not? Like I said, play!
Browning the tops of these before they overbake inside is the key to success. So you may want to bake one muffin pan at a time, right at the top of your oven. Feel free to ride your oven dial and go hotter or cooler to control the browning, but just remember that color is flavor, so you want these pretty dark.
