Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Shad and Shad Roe in Perfection
Ingredients
Directions
Prepare the fish
Purchase a thick shad from a reputable fish dealer, preferably netted before rain.
The night before cooking, wipe the shad with a damp cloth.
Rub the shad with the salt, pepper, and brown sugar mixture.
The next day, wash the shad lightly.
Season the shad with additional salt and pepper.
Broil and baste
Preheat the broiler and grease it with butter.
Place the shad on the broiler over a hot fire.
Melt some butter in a plate.
Baste the shad with the melted butter while it cooks.
Make the sauce and serve
In a bowl, mix the egg yolk, cayenne pepper, parsley, onion juice, and lemon juice.
Serve the sauce in a small boat alongside the cooked shad.
Butter the shad lightly before serving and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shad
- The main fish, whose thick flesh holds up to broiling over a hot fire.
- Coarse sea salt
- Seasons the fish and draws out surface moisture when rubbed in before cooking.
- Brown sugar
- Adds sweetness and helps the surface brown during broiling.
- Butter
- Adds fat and richness; basting keeps the surface moist and golden as it cooks.
- Egg yolk
- Emulsifies with the butter and lemon to give the sauce a smooth, thick body.
The step that matters
Basting while broiling. Sugar on the fish browns quickly over a hot fire and can scorch before the flesh is cooked through. Regular basting with melted butter adds moisture and fat, slowing the darkening and keeping the surface from drying out.
Swap the onion
How well each one fits the dish's main ingredients (pepper, sugar, butter, egg, parsley, lemon):
- Shallotfits better
- Capsicumfits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against pepper, sugar, butter, egg, parsley, lemon. Candidates are from the same food group and used in at least 100 recipes.
