Crispy-skinned Spanish mackerel with piperade

Crispy-skinned Spanish mackerel with piperade
Anne Cusack / Los Angeles Times

Good things come in small packages. Sardines and mackerel are proof of this adage. These are fish for the converted, fish for people who truly enjoy the flavor of fish. My first experience with fish of this sort came on ... Read more

Total time: 2 hours | Serves 4
Note: Thirty minutes before you are ready to cook the fish, remove it from the refrigerator so that it begins to warm to room temperature. Spanish mackerel is best served medium-rare to medium. If the fish goes straight from the fridge to the pan, it will likely not be warmed through when it is served. Spanish chorizo is available at Spanish and select gourmet markets, as well as online; La Espanola market in Harbor City makes some very good chorizos.
  • 1 large red bell pepper
  • 1 large yellow bell pepper
  • 2 tomatoes
  • 1/4 cup plus 2 tablespoons extra-virgin olive oil, divided, plus more for cooking the fish
  • 2 whole cloves garlic, peeled
  • 1/2 sweet onion, finely diced
  • 1 pinch chile flakes
  • 4 ounces finely diced dry Spanish chorizo, scraps reserved
  • 1 ounce tomato paste
  • 1 cup lobster, vegetable or chicken broth
  • 1 small bunch basil, leaves picked and cut into ribbons (stems reserved)
  • 1 small bunch opal basil, leaves picked and cut into ribbons (stems reserved)
  • Salt and pepper, to taste
  • 4 (5-ounce) fillets Spanish mackerel, skin on

Step 1Prepare the peppers: Place the red and yellow peppers on a rack set over a gas stove-top burner heated over high heat. Roast until the skin on all sides of each pepper is charred, about 5 minutes, turning frequently. (If you have an electric or ceramic stove top, roast the peppers in the oven using the broiler setting until charred on all sides.) Wrap each pepper in plastic wrap and set aside until the peppers are cool enough to handle, then peel the skin (the skin should stick to the plastic wrap). Rub the plastic wrap against the skin to loosen and remove it. Do not rinse the peppers to remove the skin, as rinsing will remove flavor. Stem and seed each pepper, then finely dice the peppers. Set aside.

Step 2Prepare the tomatoes: Score the skin at the base of each tomato with an X. Place the tomatoes in simmering water just until the skin starts to pull away at the base, about 30 seconds. Immediately remove the tomatoes and place in a bowl of ice water to stop the cooking process. When the tomatoes are cooled, peel the skins and halve the tomatoes crosswise (across the equator), then de-seed the tomatoes and cut each half into eighths. Set aside.

Step 3In a large, heavy-bottomed saucepan, heat 2 tablespoons olive oil over medium heat. Add the garlic cloves and pepper scraps, then the chopped onion, chile flakes and chorizo scraps. Cook, stirring occasionally, until the chorizo begins to render fat and the vegetables have softened and become aromatic, several minutes.

Step 4Add the tomato paste, stirring vigorously to coat the vegetables with the paste. Continue to cook until the paste darkens and begins to caramelize on the base of the pan, 1 to 2 minutes. Stir in the broth and basil stems, and reduce the heat to a gentle simmer. Simmer the piperade base, loosely covered, for 30 minutes to marry the flavors.

Step 5Remove the sauce from heat and purée using an immersion or stand blender. Strain the sauce through a fine mesh sieve (more than once if needed) to make the smoothest sauce possible. Place the sauce back in the saucepan and bring to a gentle simmer. Add another 2 tablespoons olive oil and emulsify using an immersion or stand blender. Season to taste with salt. Set the piperade sauce aside in a warm place until ready to serve the dish.

Step 6To prepare the garnish, heat a straight-sided sauté pan over medium heat until hot. Add 2 tablespoons olive oil along with the finely diced chorizo, and sauté, stirring frequently, until the chorizo has rendered its fat and is crispy. Add the red and yellow peppers, coating them with the chorizo fat as they sauté. Reduce the heat and add a pinch of salt. Continue to cook for a few minutes, stirring occasionally, to marry the flavors. Add the tomatoes, gently stirring so the tomatoes retain as much of their shape as possible. Add an additional pinch of salt, along with half of the piperade sauce. Simmer, stirring occasionally, until the sauce coats the vegetables and thickens slightly, several minutes. Remove from heat and hold in a warm place while the fish cooks.

Step 7Place a nonstick pan over high heat, adding enough oil to barely coat the pan. Season the mackerel fillets on both sides with salt. When the pan is very hot, add the fish skin-side down. The fish may curl up a bit when it hits the pan; press gently on the center of the fillet and eventually the fish will settle back down. Cook the fish for about 3 minutes over medium-high heat, lifting the corner of one of the fillets to check the color (the skin should be crisp around the edges and golden brown). If the heat is too high, the skin will color too quickly and will scorch rather than crisp. If you see this happening, reduce the heat and continue cooking until the skin crisps.

Step 8Reduce the heat and gently flip the fish over for about 30 seconds to finish cooking. Remove the fish from the pan, resting the fish on a sheet pan in a warm place (an unheated gas oven is ideal, as the heat from the pilot of a gas oven is enough to keep the fish warm).

Step 9While the fish rests, finish the garnish: Place the sauce back over the fire and double-check the seasoning. Finish the garnish by adding the basil, tasting and adjusting the seasoning for the garnish as well.

Step 10To plate the dish, spoon an equal portion of the garnish onto each plate. Spoon a bit of sauce around the garnish. Place the fish on top of the garnish and serve immediately. If you'd like, you can garnish with tiny basil leave and a touch more oil.
