Escabèche is a Spanish method of preparing fish, first with a quick, hot sear then with a long, leisurely bath in olive oil, vinegar, herbs and spices. The vinegar finishes “cooking” the fish, producing moist, flaky flesh with a tangy, refreshing flavor. Spoon the fish and sauce over greens, and an instant salad is made.
It’s hard to find fish recipes that taste better as the week goes on, but this is exactly the point of escabèche. You can eat it after 6 hours or so of marinating, or over the course of a week. While any type of white fish works well, always consider sardines or mackerel for escabèche. The spicy, vinegary sauce tames the strong flavor of fatty fish. High levels of healthy omega-3 fats and low mercury levels make fresh sardines and mackerel the perfect fish to consume. And now, you have another easy and delicious way to serve them.
Time in the Kitchen: 25 minutes, plus at least 6 hours to marinate
1 pound/450 g white, flaky fish cut into 4 pieces, or 8 whole sardines or mackerel, filleted
½ teaspoon red pepper flakes or 1 hot chile, thinly sliced (2.5 ml)
2 tablespoons chopped parsley (optional) (30 ml)
Season fish with paprika a generous sprinkle of salt.
Melt butter and 1 tablespoon (15 ml) olive oil in a skillet over medium-high heat. Sear the fish on both sides until lightly browned, about 2 minutes per side. The fish should be browned, but not cooked through. Remove from the skillet and place in a glass or ceramic dish just big enough so the fish fits snugly.
Wipe out the skillet to remove any black bits of fish leftover. Heat another tablespoon of olive oil over medium heat. Add shallots, garlic and bell peppers. Cook just long enough to soften the shallot and bell pepper, about 4 minutes. Add the vinegar, salt, bay leaves, thyme sprigs and red pepper flakes. Bring to a low simmer for 5 minutes then add the remaining ¾ cup olive oil.
Pour the hot mixture of oil and vinegar over the fish, making sure most, if not all, of the fish is submerged. Cool to room temp. Cover with plastic wrap and refrigerate at least 6 hours before eating. The fish will stay fresh and can be eaten over the next 3 to 5 days or so.
