Step 1

In a small skillet, toast the cumin and coriander seeds over low heat, shaking the pan occasionally, until fragrant, about 2 minutes. Transfer to a spice grinder and let cool. Pulse until finely ground.

Step 2

In a food processor, combine the ground seeds with the cilantro, parsley, mint, preserved lemon, garlic, paprika, lemon juice, crushed red pepper and saffron, if desired. Pulse until a coarse paste forms. With the processor running, drizzle in the olive oil in a slow, steady stream. Scrape the chermoula into a medium bowl and season with salt and pepper.
