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 ↓
Lemon-Pepper Grilled Catfish
Ingredients
Directions
Marinate
Purée lemon juice, green onions, and olive oil in a blender.
Pour the mixture into a shallow dish and add salt and black pepper to taste.
Add catfish fillets, turning to coat.
Refrigerate, covered, for 12 to 24 hours to marinate.
Make the lemon-butter sauce
Simmer wine and shallot over medium heat until wine has evaporated.
Add cream and simmer until reduced by half.
Remove from heat.
Gradually whisk in butter cubes, a few at a time, until sauce thickens and is thoroughly blended.
Return pan briefly to heat to help incorporate butter, if necessary.
Season to taste with lemon juice, salt, and white pepper.
Grill and serve
Preheat grill or broiler.
Mix flour and baking powder in a shallow dish or on wax paper.
Drain excess marinade from fillets and pat dry with paper towels.
Lightly dredge catfish fillets in flour mixture.
Place fillets on an oiled grill rack or broiler pan rack.
Grill or broil catfish about 4 inches from the heat source for about 3 to 4 minutes on each side, or until fish flakes easily when tested with a fork.
Serve with lemon butter sauce and garnish with lemon wedges and green onions.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Whisked in cold, it emulsifies with the reduced cream to give the sauce body and a silky texture.
- Heavy cream
- Reduced by simmering, it thickens and gives the sauce a rich, smooth body.
- Olive oil
- Carries fat-soluble flavors from the marinade and keeps the fish moist during grilling.
- All-purpose flour
- Forms a light coating on the fillets that helps them brown and hold together on the grill.
- White wine
- Simmered with shallot until evaporated, it leaves a bright, aromatic base for the sauce.
The step that matters
Drain and pat the fillets dry before dredging. Surface moisture from the marinade would make the flour pasty instead of a light coating, which prevents proper browning and sticking on the grill.
