Why it works: Onion and allspice are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 4,270 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Sprats, Baked
Ingredients
Directions
The book says “a gentle oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the sprats
Clean the sprats and remove the heads.
Draw them at the gills.
Dry with a soft cloth.
Bake
Place the sprats in a dish and cover with equal parts vinegar and water.
Add the bay leaf, onion, allspice, salt, and whole peppercorns to the liquid.
Cover the dish tightly.
Bake in a gentle oven at 300°F (150°C) until done, about 30 to 45 minutes.
Finish and seal
Once cooled, remove the cover.
Pour cold vinegar over the sprats.
Seal them up.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sprats
- Are the main fish that is cooked and preserved in the dish.
- Vinegar
- Acidifies the liquid, helping preserve the fish and giving it a tangy flavor.
- Bay leaf
- Adds a subtle aromatic flavor to the cooking liquid.
The step that matters
Baking gently with the dish tightly covered. A gentle oven and a tight cover let the fish cook slowly in the vinegar and water without drying or breaking apart. Sealing traps steam so the bones soften through gradual heat, which matters for a dish meant to be eaten bones and all.
Swap the onion
How well each one fits the dish's main ingredients (vinegar, allspice):
- Mustardfits better
- Cucumberfits better
- Horseradishfits better
- Onionthe original
Fit is the average pairing score against vinegar, allspice. Candidates are from the same food group and used in at least 100 recipes.
