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
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Remove the roes from the shad, clean, and dry thoroughly.
Cut the shad into straight halves and lay it with the roes on a well-heated and greased grill over moderate heat.
Broil
Cover the grill to cook through while browning, and turn the shad only once.
Finish and serve
Once done, transfer to a warm dish and spread the butter on top, then season with pepper and salt.
Place in a 350°F (175°C) oven for a moment, then 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
- Is the main fish, cooked through on the grill while its surface browns.
- Butter
- Adds richness and moisture, melting over the hot fish to carry flavour.
The step that matters
Turning the shad only once. Fish flakes apart when handled repeatedly, and each turn breaks the browned surface. Turning once lets a crust form and keeps the halves intact while the interior cooks through.
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.
