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 ↓
Baked Shad with Roe Sauce
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the fish
Remove the roe from the shad, then clean, wash, and dry the fish.
Make stuffing by mixing bread crumbs, melted butter, grated onion, chopped parsley, chopped tomato, Worcestershire sauce, salt, and pepper.
Stuff the fish, sew it closed, and place it in a baking pan.
Top the fish with slices of raw tomato and sprinkle with salt and pepper.
Bake the fish
Bake at 400°F (200°C) for one hour, basting frequently with butter and hot water.
Before removing from the oven, pour over the fish a mixture of sherry, Worcestershire sauce, lemon juice, and cayenne.
Make the roe sauce
For the sauce, parboil the roe in salted water with cloves, bay leaf, and parsley.
Remove the skin from the roe and mash it finely.
Melt butter, stir in tomato sauce, lemon juice, and sherry, and cook for five minutes.
Add the mashed roe to the sauce and serve with the fish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shad
- Forms the main body of the dish, cooked whole so it stays moist while baking.
- Bread crumbs
- Absorb the butter and juices in the stuffing, giving it a moist, tender body.
- Melted butter
- Adds fat that keeps the fish and stuffing moist and promotes gentle browning.
- Roe
- Gives the sauce its rich, creamy body when mashed and cooked into it.
- Sherry
- Adds acidity and aroma to the baste and the sauce.
- Tomato
- Adds moisture and mild acidity to the stuffing and the topping.
The step that matters
Basting during the bake. Fish is lean and dries out quickly in dry oven heat. Frequent basting with butter and hot water coats the surface with fat and moisture, keeping the flesh tender.
Swap the onion
How well each one fits the dish's main ingredients (bread, butter, parsley, tomato, sauce, pepper, sherry):
- Capsicumfits better
- Carrotfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against bread, butter, parsley, tomato, sauce, pepper, sherry. Candidates are from the same food group and used in at least 100 recipes.
