Why it works: Horseradish and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 2,646 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Boiled Fresh Cod
Ingredients
Directions
Poach the fish
Place the fish in a fish kettle or tie it in a cloth.
Add the fish to boiling water with salt and horseradish.
Simmer until cooked through.
Transfer the fish to a folded napkin on a dish.
Serve with drawn butter, oyster sauce, or egg sauce.
Make the chopped fish
When cold, chop the fish finely.
Pour drawn butter or egg sauce over the chopped fish and add pepper.
Warm thoroughly, stirring to prevent burning.
Shape into rolls or desired form and brown before the fire.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh cod
- Provides the flaky protein that forms the body of the dish.
- Drawn butter
- Adds richness and moisture to the fish and keeps it from drying out.
- Egg sauce
- Adds moisture and a creamy, rich texture to the chopped fish.
- Scraped horseradish
- Adds a sharp, pungent aroma that flavours the poaching water and fish.
The step that matters
Warm thoroughly, stirring to prevent burning. Cod is lean and the sauces contain butter and eggs, which can scorch or curdle when heated hard. Gentle, constant stirring spreads heat evenly and keeps the sauce smooth while the fish warms through.
