Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Cream Pickerel
Ingredients
Directions
Prepare and bake the fish
Clean the fish and score the backbone in several places if large.
Bake the fish slowly, pouring 1 cup of boiling water over it at first.
Baste the fish often with butter and water while baking.
Once done, place the fish on a hot-water dish.
Make the cream sauce
In the dripping pan, add 1 cup of milk with a pinch of baking soda and heat.
Stir in 2 tablespoons of butter and 1 teaspoon of corn-starch mixed with water.
Add chopped parsley and boil once to thicken.
Season with pepper and coarse sea salt to taste, then pour over the fish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the body of the cream sauce and supplies its smooth, rich texture.
- Corn-starch
- Thickens the milk into a smooth sauce as its starch gelatinizes with heat.
- Butter
- Adds fat for richness and flavor, and helps keep the fish moist while baking.
- Baking soda
- Raises the pH of the milk slightly, which helps it stay smooth when heated.
The step that matters
Stir the corn-starch into the milk and boil it once. Cornstarch must be fully dispersed in liquid before heating, or it clumps. It thickens only once it reaches a boil, so the sauce needs to come to a full boil to reach its final texture.

Fit is the average pairing score against salmon, butter, milk, corn, pepper. Candidates are from the same food group and used in at least 100 recipes.
