Bring 400 ml of water (roughly 1.33× the dry couscous weight) to a gentle simmer. Add the saffron threads to 50 ml of the warm white wine/stock (reserve the rest for braising) to bloom for 5–10 minutes—this releases the saffron’s color and aroma so it infuses evenly into the couscous.

Heat 1 tablespoon (15 ml) olive oil in a medium saucepan over medium heat. Add the dry Israeli couscous and toast, stirring, for 2–3 minutes until some pearls show light golden edges—this toasting gives the couscous a nutty depth and prevents a flat starchy taste.

Pour the simmering water and the saffron-infused 50 ml wine/stock into the toasted couscous, season lightly with salt, bring to a gentle simmer, cover, and lower the heat. Cook according to package directions (usually 8–10 minutes) until pearls are tender but still separate. Remove from heat, stir in 1 tablespoon olive oil and 10 g butter (optional) to give shine and mouthfeel, then cover and let rest 5 minutes. Fluff with a fork before serving—fluffing prevents clumping and keeps grains light.

While the couscous cooks, prepare the braised fennel: heat 2 tablespoons (30 ml) olive oil in a wide sauté pan over medium heat. Add the finely chopped shallot and a pinch of salt—sweat without browning for 3–4 minutes so the shallot softens and sweetens, building the dish’s base aroma.

Add the thinly sliced fennel to the pan, season with salt and pepper, and increase the heat to medium-high for 2 minutes to encourage light caramelization on the edges—this adds a subtle sweet-savory contrast. Then deglaze with 150 ml of the reserved white wine/stock, scraping the fond (browned bits) to incorporate flavor.

Reduce the heat to low, cover the pan, and braise the fennel gently for 12–15 minutes until very tender and translucent. Low, slow braising melts fennel’s fibers and concentrates sweetness; keep the lid on most of the time to trap steam and soften the slices evenly. Taste and adjust seasoning—if the braising liquid is too tart, add a pinch of sugar or 5 g butter (optional) to round acidity.

Prepare the caper-persillade (a lemony parsley-garlic finishing relish): combine the rinsed capers, minced garlic, chopped parsley, lemon zest from both lemons, and 1 tablespoon (15 ml) olive oil. Add 1–2 teaspoons of lemon juice (to taste), season with freshly ground black pepper, and set aside for the flavors to marry. The capers bring brine; the lemon and parsley add bright lift that contrasts the richness of the fish.

Pat the cod fillets very dry with paper towels—dry surfaces sear more efficiently and form a golden crust. Season both sides with salt and pepper and let sit 5 minutes at room temperature; this relaxes the chill and helps even cooking.

Heat a large nonstick or stainless-steel skillet over medium-high heat until hot, then add 2 tablespoons (30 ml) olive oil and swirl to coat. When oil shimmers (but not smoking), place the cod fillets skin-side down (if present). Press gently for 10–15 seconds with a spatula to ensure full skin contact—this prevents curling and produces an even, crisped skin.

Sear the cod skin-side down for 3–4 minutes without moving it so the skin crisps; you should see the cooked flesh move up the side as the fillet cooks. Flip carefully and sear the flesh side 1–2 minutes until just cooked through—cod is best taken off heat at about 52–54°C (125–130°F) for a moist, flaky texture. If using butter, add the 40 g now and spoon the foaming butter over the fillets for 20–30 seconds to baste and add gloss.

To plate: spoon a generous bed of saffron couscous in the center, arrange braised fennel alongside or partially over the couscous, and top with a cod fillet. Spoon the caper-persillade over the fish and around the plate. Finish with a drizzle of remaining olive oil (about 1 tsp per plate) and a few extra chopped parsley leaves for color. Serve immediately so the contrast of hot couscous/fennel and bright persillade is at its best.

Final seasoning: taste and finish each plate with a small squeeze (about 1/2 tbsp) of fresh lemon juice over the fish and a light grind of black pepper. The acid brightens the whole dish and ties the flavors together.
