General tips
Halibut goes from buttery to cottony in a 5-degree window. 122°F is the floor for opaque, holding texture; 127°F is the absolute ceiling. Above that, the lean white flesh dries out fast. There is no margin - set your bath precisely.
Salt and butter in the bag are mandatory. Halibut has so little fat of its own that it needs help. Two pats of butter on top of each fillet, plus a generous pinch of salt and a few cracks of pepper, is the minimum for a flavorful result.
Brown butter is the natural pairing. After the bath, drain the bag liquid into a small saucepan, add a few tablespoons of butter, cook over medium until the milk solids brown and smell like hazelnuts. Spoon over the halibut and finish with capers and parsley.
Sear briefly only if you want a Maillard exterior. Some prefer their halibut pure and simple from the bath. If you want a sear, pat the fillet bone-dry, hot pan, 30 sec per side, no more. Going longer cooks the interior past the texture you carefully created.
Anti-tip: don't pair halibut with bold, smoky flavors. Its delicate sweetness gets steamrolled by anything stronger than brown butter or olive oil. Save the BBQ rubs and chili glazes for tuna or salmon. Halibut wants quiet, elegant treatments only.
