Why it works: Tarragon and capers match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 379 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Stewed Halibut
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Season the halibut pieces lightly with coarse sea salt and let rest for 30 minutes.
Place the halibut in a large, deep dish.
Sprinkle cayenne pepper, ground ginger, and grated nutmeg over the fish.
Add small pieces of fresh butter rolled in grated bread.
Pour in ½ pint of tarragon vinegar.
Cook and finish
Cook in a slow oven at 300°F (150°C), basting frequently with the liquid.
When nearly done, add a large tablespoon or more of capers or pickled nasturtiums.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Halibut
- Forms the main body of the dish, becoming firm and flaky as it cooks gently.
- Fresh butter
- Adds richness and moisture, keeping the fish from drying out in the oven.
- Grated bread
- Soaks up butter and liquid, helping to thicken the juices and add body.
- Tarragon vinegar
- Adds acidity that brightens the flavour and tenderises the fish slightly.
- Capers or pickled nasturtiums
- Add a sharp, briny bite that cuts through the richness of the butter.
The step that matters
Basting during the slow oven stage. Basting keeps the surface moist and carries the vinegar and butter over the fish, so it cooks evenly and does not dry out. Slow heat also keeps the flesh tender and prevents it from toughening.
Swap the ginger
How well each one fits the dish's main ingredients (pepper, nutmeg, butter, bread, tarragon, vinegar, capers):
- Parsleyfits better
