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 ↓
Baked 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the stuffing
Preheat the oven to 350°F (175°C).
Cut off the head of the shad if preferred and remove the backbone, leaving 2 inches near the tail.
In a skillet, melt 1 tablespoon of butter and fry the chopped onion until soft.
In a bowl, combine the fried onion, soaked bread, 1 tablespoon of butter, salt, pepper, and parsley or sage.
Heat the mixture thoroughly.
Remove from heat and stir in the beaten egg yolks.
Stuff and bake
Stuff the mixture into the shad and secure it with kitchen twine.
Place the fish in a baking pan, baste with remaining butter, and add water to the bottom of the pan.
Bake for about 30-40 minutes or until cooked through.
Make the sauce and serve
For the sauce, mash the hard‑boiled egg yolks into a smooth paste, then mix in olive oil, mustard, pepper, and vinegar to taste.

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 that is stuffed, baked and carries the whole dish.
- Stale bread
- Soaked and squeezed, it absorbs moisture and gives the stuffing body without making it wet.
- Egg yolks
- Beaten into the stuffing, they bind it and set as it bakes, holding it together.
- Butter
- Adds richness and fat, and basting the fish helps keep its surface moist while baking.
- Onion
- Softened in butter first, it adds sweetness and savory depth to the stuffing.
- Hard-boiled egg yolks
- Mashed into a paste, they give the sauce a smooth, rich body.
The step that matters
Stuff and bake without overfilling. Packing the stuffing too tightly can leave the centre undercooked and split the skin, while the egg yolks need gentle heat to set. Bake until the fish is cooked through, checking it at the lower end of the time range.
Swap the onion
How well each one fits the dish's main ingredients (bread, butter, pepper, parsley, egg, sauce, olive):

Fit is the average pairing score against bread, butter, pepper, parsley, egg, sauce, olive. Candidates are from the same food group and used in at least 100 recipes.
