Harissan is From preparation to the plate, this recipe takes around 45 minutes. If you have paprika, pepper, ground cumin, and a few other ingredients on hand, you can make it.
Snap off and discard stems of 2 ounces dried ancho or California chilies (see notes). Shake out and discard seeds. Rinse chilies and cut or break into about 1/2-inch pieces. Soak in 1 cup hot water until soft, about 20 minutes. Lift chilies out (reserving soaking water) and transfer to a blender or food processor.
Add 1/3 cup of the reserved water, 3 tablespoons each lemon juice and olive oil, 1 tablespoon paprika, 1 1/2 teaspoons cayenne, 1 teaspoon ground coriander, 1 teaspoon salt, 1/2 teaspoon ground cumin, and 1/8 teaspoon pepper; whirl until smooth. If thicker than desired, blend in 2 to 3 more tablespoons reserved water.
