Fish Couscous With Onion

Moroccan fish cookery at its most refined. The sweet onion t’faya here is a Moroccan specialty: very thinly sliced onions slowly browned with raisins, sugar, and a full lineup of warm spices until they turn into a jammy, deeply flavored confit. Halibut poaches gently in that sweet onion bed, picking up every note of saffron, turmeric, cinnamon, and allspice without drying out.

Crushing the saffron threads with the salt is the trick for pulling maximum color and flavor from the most expensive spice in your kitchen. A mortar and pestle or the flat side of a chef’s knife turns the threads into a coarse powder that distributes evenly through the onion mixture. That same blend cooked in oil and butter until it foams blooms the spices before the onions even go in.

Whole wheat couscous soaks up the poaching liquid, almonds toasted in canola oil add crunch, and everything stacks together on a shallow platter: couscous first, fish and onion t’faya on top, almonds scattered over. Twenty to 25 minutes of slow onion work is where the real flavor lives.

Chef Tips

• Slice the onions as thin as your knife or mandoline allows. Thicker slices take longer to caramelize and can stay stringy.
• Do not rush the onions. A full twenty-five minutes on medium heat is what separates a flat onion sauté from a proper t’faya with depth.
• Use halibut, cod, or another firm white fish. Flaky fish like sole or flounder falls apart in the onion mixture.
• Toast the almonds just until they begin to turn gold, about one minute. They keep toasting off the heat, and burnt almonds ruin the whole platter.

Variations

• Swap halibut for boneless chicken thighs. Increase the poaching time to about 20 minutes.
• Use dried apricots or prunes in place of raisins for a deeper dried-fruit note.
• Finish with a drizzle of honey over the onions for an even sweeter version closer to traditional tagine t’faya.
