Why it works: Pepper and parsley 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 ↓
Broiled Shad
Ingredients
Directions
Prepare
Remove the roes from the shad and clean it thoroughly.
Dry the shad and cut it into straight halves.
Cook
Lay the halves with the roes on a well-heated and greased grill over moderate heat.
Cover the grill to ensure even cooking while browning.
Turn the shad only once.
Finish and serve
Once cooked, transfer to a warm dish and spread the butter on top.
Sprinkle with a little pepper and coarse sea salt.
Place the fish in the oven for a moment.
Garnish with fresh parsley before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shad
- Forms the dish; its flesh cooks to firm flakes over heat.
- Butter
- Adds richness and a glossy coating that helps keep the fish moist.
The step that matters
Turn the shad only once. Repeated turning breaks the browned crust that forms on the grill, so the fish sticks and tears. A single turn, after the surface has set and released, keeps the halves intact and evenly browned.
Swap the walnut
How well each one fits the dish's main ingredients (butter, pepper, parsley):
- Chickpeafits about as well
- Black-eyed peafits about as well
- Walnutthe original
- Beansfits about as well
Fit is the average pairing score against butter, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
