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 ↓
To Bake Red Snapper
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
Clean the fish, remove the head, and draw out the entrails without cutting it open.
In a bowl, mix the bread crumbs, chopped onion, chopped parsley, pepper, and salt.
Stuff the fish with the seasoning mixture.
Bake
Grease a baking dish with butter and add water to a depth of 2 inches.
Sprinkle a little flour over the water.
Place the fish in the dish and bake in a preheated oven at 350°F (175°C) for 1.5 hours.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Red snapper
- Is the main protein, cooked whole so the flesh stays moist in the oven.
- Stale bread crumbs
- Absorb juices and onion flavor, keeping the stuffing moist and lightly textured.
- Onion
- Adds aromatic sharpness that mellows and perfumes the fish as it bakes.
- Parsley
- Adds fresh, green aroma that brightens the rich, savory stuffing.
The step that matters
Bake in the water bath. Water in the dish creates a gentle, steamy environment around the fish, so it cooks evenly and does not dry out at the surface during the long bake.
Swap the onion
How well each one fits the dish's main ingredients (snapper, bread, parsley, pepper, butter, flour):
- Shallotfits better
- Capsicumfits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against snapper, bread, parsley, pepper, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
