Why it works: Pepper and tomato are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,923 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Fried Shad
Ingredients
Directions
Prepare the fish
Scale and split the shad down the belly, then wash it in cold water.
Dry the fish with a linen cloth, then season it inside and out with salt and pepper, and dredge it with flour on both sides.
Fry the fish
Heat a frying pan with butter and lard until hot, then lay the fish in whole.
Cover the pan and fry the fish slowly for 40 minutes, turning it after 20 minutes.
Once cooked, lift the fish into a warm chafing dish.
Make the gravy
In the frying pan, add browned flour and hot water to the drippings, and let it boil for 5 minutes, stirring well.
Stir in the tomato ketchup and pour the gravy into a serving dish.

Flour and butter 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
- Shad
- Provides the main body of the dish, cooked whole in fat until flaky and golden.
- Flour
- Dredging coats the fish so its surface browns and crisps during frying.
- Butter
- Adds fat and browning flavor to the frying pan for the fish.
- Lard
- Adds fat with a high smoke point for slow frying and a crisp surface.
- Browned flour
- Thickens the pan drippings into a gravy and adds a toasted, nutty flavor.
- Tomato ketchup
- Adds sweetness and acidity to the gravy, giving it a tangy flavor.
The step that matters
Slow frying with the lid on. Frying slowly over gentle heat cooks the fish through without burning the flour coating. Turning it once at the midpoint lets both sides brown evenly.
Swap the tomato
How well each one fits the dish's main ingredients (pepper, flour, butter, ketchup):
- Capsicumfits better
- Shallotfits better
- Turnipfits better
- Tomatothe original
Fit is the average pairing score against pepper, flour, butter, ketchup. Candidates are from the same food group and used in at least 100 recipes.
