Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Shad Roe Creamed and Curried
Ingredients
Directions
Cook and marinate
Cook the roe in salted, acidulated water, simmering gently to avoid breaking the skin.
Cut the roe into scallops or cubes, marinate with lemon juice, onion juice, salt, and pepper, then cover and let stand for several hours.
Make the sauce and serve
Prepare a white sauce in a double boiler using butter and flour, then gradually add milk.
Add the marinated roe to the white sauce and let it stand over hot water to reheat.
For a variation, add 1 tablespoon of curry powder with the flour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shad roe
- Forms the main body of the dish, giving it a tender, delicate texture once cooked.
- Butter
- Provides fat and richness, and combines with flour to form the base of the white sauce.
- Flour
- Thickens the milk and butter into a smooth white sauce as it cooks.
- Milk
- Forms the liquid of the white sauce, adding moisture and creaminess.
- Lemon juice
- Adds acidity that firms the roe's surface and brightens the flavor during marinating.
- Curry powder
- Adds warm, aromatic spice flavor to the sauce in the variation.
The step that matters
Cooking the roe gently. Simmering gently keeps the roe's delicate membrane from splitting. Vigorous boiling can break the skin and let the roe's contents escape, leaving the roe dry and ragged.
Swap the onion
How well each one fits the dish's main ingredients (roe, lemon, pepper, butter, flour, milk):

- Onionthe original
Fit is the average pairing score against roe, lemon, pepper, butter, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
