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 them rest for 30 minutes.
Remove the halibut from the salt and place it 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 on top.
Pour in the tarragon vinegar.
Bake and serve
Place the dish in a 300°F (150°C) oven and cook the halibut, basting frequently with the liquid.
When nearly done, add 1 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, cooking gently to a flaky texture.
- Fresh butter
- Adds richness and moisture, melting into the fish and crumbs as it bakes.
- Grated bread
- Coats the butter pieces, helping to thicken the liquid and add body to the topping.
- Tarragon vinegar
- Adds acidity and tangy flavor, and forms the cooking liquid for basting.
- Capers or pickled nasturtiums
- Add sharp, briny acidity that cuts through the richness of the butter.
The step that matters
Basting the halibut in the oven. Frequent basting keeps the fish moist in gentle heat, so the liquid and butter do not dry out and the flesh cooks evenly rather than drying at the edges.
Swap the ginger
How well each one fits the dish's main ingredients (pepper, nutmeg, butter, bread, tarragon, vinegar, capers):
- Parsleyfits better
- Marjoramfits better
- Thymefits better
- Gingerthe original
Fit is the average pairing score against pepper, nutmeg, butter, bread, tarragon, vinegar, capers. Candidates are from the same food group and used in at least 100 recipes.
