How To Make Jamie Oliver The Best Fish Baps with Mushy Peas & Tartare Sauce
- Warm the baps: Preheat the oven to 130°C/250°F/gas ½ and place the baps inside to warm through.
- Cook the potatoes: Thinly slice the potato (about 0.5cm) and place in a small pan. Cover with boiling water, lid on, and bring to a boil.
- Prepare the fish: On greaseproof paper, season the fish with salt, pepper, and cayenne. Coat with flour.
- Fry the fish: Heat 2 tablespoons olive oil in a frying pan over high heat. Add the fish and cook until golden. Grate Parmesan over the top when flipping.
- Cook the peas: Add frozen peas to the potato pan, rip in the leafy top of the mint, and cover.
- Make tartare sauce: Blend cornichons, capers, lettuce, yoghurt, parsley leaves, and lemon juice in a food processor. Season to taste and pour into a bowl.
- Blend peas and potato: Drain, blend until smooth in the processor, and season.
- Assemble and serve: Remove baps from the oven. Fill with fish, mushy peas, tartare sauce, pinches of cress, and lemon wedges on the side.
