How to Make It
Preheat the oven to 375°. In a medium bowl, whisk the flour with the paprika, salt, baking powder, baking soda and pepper. In a large bowl, whisk the buttermilk with the eggs, butter, harissa, chives, onion, scallions, parsley and Worcestershire until smooth. Whisk into the dry ingredients just until combined. Stir in the cheese and chopped pimientos.
Using a 1/3-cup measure, scoop the batter into 12 muffin cups. Bake for about 18 minutes, until golden brown and a toothpick inserted in the middle comes out clean. Let cool for 5 minutes, then unmold and serve with pimento cheese.
Harissa, the brick-red Tunisian chile paste, is available at specialty food stores and markets like Whole Foods.
