Ingredients

Contains: fish (auto-detected from the ingredients and method; we can miss things, so check labels)

  • For the pickled pearl onions
  • For the apple-fennel salad

Directions

Make the pickling liquid

  1. Mix water, vinegar, sugar, salt, garlic, mustard seed, peppercorns, ginger, and jalapeño pepper in a medium saucepan.

  2. Cook over medium heat, stirring occasionally until it comes to a simmer and salt and sugar are dissolved.

  3. Cool.

Pickle the onions

  1. Heat grapeseed or canola oil in a small sauté pan over medium-high heat.

  2. Add onions and sauté until lightly caramelized.

  3. Add onions to the saucepan with the vinegar mixture.

  4. Let stand for 1 hour to pickle.

  5. Strain the onions from the pickling juice.

  6. Place pickling juice in a small saucepan.

  7. Simmer for 15 to 20 minutes or until reduced to 1/2 cup.

  8. Remove from the heat and set aside.

Make the apple-fennel salad

  1. Toss diced apples, fennel bulb, orange sections, and raisins in a small bowl.

  2. Add 6 tablespoons of the reduced pickling juice and 6 teaspoons of the fennel fronds.

  3. Stir until combined.

  4. Set aside.

Grill the catfish and serve

  1. Prepare a grill or preheat the broiler.

  2. Rub catfish fillets with olive oil and season both sides with salt and pepper.

  3. Oil a grill rack or broiler pan rack.

  4. Grill or broil fillets about 4 inches from the heat source for 2 to 3 minutes on each side, or until fish flakes easily when tested with a fork.

  5. Place a small mound of apple-fennel salad on each serving plate.

  6. Arrange pickled pearl onions on plates and top with grilled catfish.

  7. Spoon remaining 2 tablespoons pickling juice around plates and sprinkle with remaining 2 teaspoons fennel fronds.

  8. Drizzle a little olive oil over the plates and serve.

    Shared aroma: isobutyraldehyde (malty, green).

Vinegar and mustard share little aroma chemistry, yet 14,067 recipes mention both: they likely 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

White pearl onions
Soften in the pickling liquid, becoming tangy and sweet while keeping a crisp bite.
Sugar
Balances the sharp vinegar and rounds out the pickling liquid's flavor.
Rice vinegar
Provides the acidity that pickles the onions and brightens the salad.
Catfish fillets
Provide the mild, flaky protein that cooks quickly over high heat.
Granny smith apples
Add crisp texture and tartness to the salad.
Golden raisins
Add pockets of sweetness and moisture to the salad.

The step that matters

Grilling or broiling the catfish. Fish is lean and cooks fast, so it can dry out or overcook quickly. Removing it once it flakes easily keeps it moist, because proteins tighten and squeeze out moisture when overheated.

Flavor stand-ins for the jalapeno

How well each one fits the dish's main ingredients (rice, vinegar, sugar, garlic, mustard, ginger, pepper):

  1. Turmericbetter flavor fit
  2. Cinnamonbetter flavor fit
  3. Corianderbetter flavor fit
  4. Jalapenothe original

Fit is the average pairing score against rice, vinegar, sugar, garlic, mustard, ginger, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
