Halibut with Lemon Caper Sauce
Pan-seared halibut fillets in a quick lemon, caper and butter pan sauce. Four servings in 25 minutes.
Leave the fish alone. A fillet that is nudged too soon sticks and tears, while one left for 4 minutes releases itself from the pan and comes away golden. Halibut is lean and firm, which makes it forgiving, but it dries out quickly if it is cooked past opaque. Pat it dry before it goes in.
The sauce takes less time than the fish. Reduce the sauce by half and it turns sharp and glossy, with lemon doing most of the work. Capers bring the salt. Finish with cold butter off the heat, which melts into the reduced stock and gives it a light, silky body without any flour.
Rinse the capers first. That takes off some of the brine. Spoon the sauce around the fish rather than over it, so the crust stays crisp. Serve with roasted asparagus, steamed broccoli or a rocket salad. Leftover halibut flakes into a salad.

Swaps and Variations
- An eighth of a teaspoon of garlic powder per clove is the usual stand-in when you are out of fresh garlic — it will not caramelise the same way, but it carries the flavour.
- Vegetable stock in place of the chicken stock makes this meat-free without changing the method, if that is what you need.
