Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Codfish Steak.
Ingredients
Directions
Prepare the fish
Cut the codfish into steaks about 1.5 inches thick and sprinkle with coarse sea salt.
Let the steaks stand for 2 hours.
Dredge the codfish steaks in cornmeal.
Render the pork fat
Dice the salt pork and fry it in a pan until all the fat is rendered.
Remove the crisp bits of pork.
Fry and serve
Heat the pork fat until smoking hot.
Fry the steaks until dark brown on both sides.
Squeeze lemon juice over the steaks and add freshly ground pepper.
Serve with hot, well-buttered Johnny cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codfish
- Forms the main body of the dish, cooking to a flaky, tender texture.
- Cornmeal
- Coats the steaks, forming a crisp, browned crust when fried.
- Salt pork
- Renders fat for frying and leaves crisp bits that add savory flavor.
- Lemon juice
- Adds acidity that brightens the rich, fried fish.
The step that matters
Heat the pork fat until smoking hot. Fish placed in fat that is not hot enough absorbs more oil and steams instead of browning. A properly hot fat sears the cornmeal coating quickly, producing a crisp, dark crust while keeping the inside moist.
Swap the lemon
How well each one fits the dish's main ingredients (pork, pepper, butter):
- Lemonthe original
- Mangofits about as well
- Plumfits less well
- Avocadofits less well
Fit is the average pairing score against pork, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
