1/4 cup (1/2 stick) unsalted butter, room temperature
1/4 cup chopped fresh mint
3 tablespoons harissa paste
1 teaspoon kosher salt or to taste
Process all ingredients in food processor or mini-prep food processor until smooth.
Harissa paste is a spicy North African red chile paste and is available at Middle Eastern markets and some specialty foods stores, and online at The Spice House. Delicious as replacement to butter for a roast chicken for a taste of Morocco.
