Pickled Halibut
Proceed in the same manner as for pickled salmon, using ten pounds of halibut in one piece instead of the salmon.
This is a cross-reference, not a standalone recipe: it sends you back to the pickled salmon entry and swaps the fish. Everything that matters therefore depends on that earlier method, and on the fact that halibut behaves nothing like salmon in a poaching kettle.
- Read the salmon recipe firstWithout the pickled salmon entry you have no cooking liquid, no vinegar quantity and no spices. The usual pattern in books of this kind is to simmer the fish in salted water, cool it, then cover it with spiced vinegar, though recipes differ over whether vinegar goes into the cooking liquid as well. Do not attempt this from the halibut line alone.
- Ten pounds in one pieceThat is a banquet quantity, roughly 20 to 25 servings, and it would have needed a vessel large enough to hold the piece whole. Scale to a 2 to 3 lb centre-cut piece for a household and reduce the pickling liquid to match, keeping the fish fully submerged.
- Halibut is lean where salmon is fatThis is the hinge. Salmon tolerates a long poach because its fat keeps it moist; halibut turns dry and cottony. Bring the liquid barely to a shiver, not a boil, and do not poach a thick centre cut as long as the salmon timing directs, while still cooking it through.
- Vinegar strengthHousehold vinegar of this period varied widely in acidity. Use a standard 5 percent cider or white wine vinegar and do not dilute it further than the original directs, since the acid is doing the preserving work as well as the flavouring.
- Cool in the liquid, then pack coldLet the fish cool in its poaching liquid so it does not shed moisture, then lift it whole, drain, and pour the spiced vinegar over it. Pouring it cold is safer with halibut, as hot vinegar risks breaking up the cooked flakes.
- Storage is the real changeBooks of this period kept pickled fish in a covered crock in a cool cellar for weeks. Treat it instead as a refrigerated dish: covered, fully under the vinegar, and eaten within three or four days. It is not a shelf-stable preserve, and cooked fish held at room temperature in a weak pickle is exactly the wrong environment to gamble on.
- ServingBest cold, sliced, with some of the pickle spooned over. The recipe itself specifies no accompaniments.
Pickled fish belongs to a long line of cooked-then-soused preparations that runs from Iberian and Latin American escabeche through English souse and the "pickled salmon" of British and American cookbooks, all of them ways of buying a few extra days from a fish in a kitchen without mechanical cold. Halibut suited the form because the New England and North Atlantic fishery landed it in quantity and in very large fish, so a ten-pound piece "in one piece" was a plausible market request rather than an extravagance, and its firm white flesh holds a slice well after a night in vinegar.
