Grilled Sea Bass with Romesco Sauce
Romesco sauce originates from the fishing community in Catalonia, Spain. A place where red peppers, garlic and a bit of piment are well-entrenched in the local cuisine. For this recipe for grilled sea bass, I needed a sauce with enough flavour to enhance the fish without being overpowering. Also, the dish needed to pair well with a rosé from Commanderie de Peyrassol. But, as you know, I like a challenge, and this one was a bit of culinary architecture. The result is a delicious romesco-inspired sauce with grilled sea bass.

Grilled, Herbed Chilean Sea Bass with Romesco
This Romesco-esque sauce is a take on the pungent Spanish version which includes garlic (which we don't eat) and almonds. My version includes pistachio paste and culinary lavender buds for a touch of Provence.
Ingredients
For the Romesco Sauce:
- 1 large red bell pepper
- 3 large Roma tomatoes
- 1 tbsp Ají Amarillo purée or 1 teaspoon hot paprika
- 1 tbsp pistachio paste or other nut paste
- 1/3 cup extra virgin olive oil
- juice of 1/4 lime
- 1/2 tsp Salt
For the Fish:
- 2 sprigs fresh basil
- 10 sprigs fresh thyme
- 1 tsp culinary lavender buds
- 1/2 tsp kosher salt
- 1/4 tsp freshly ground black pepper
- 3 tbsp extra virgin olive oil
- 1 1/2 lbs Chilean sea bass 1-inch thick, in four pieces
- fresh parsley chopped for garnish
Instructions
To Make the Romesco-esque Sauce:
- Heat your grill to high.
- Blacken the red pepper on all sides.
- When fully black, remove from the grill and place in a paper bag. Close and let pepper steam for 10 minutes.
- While pepper is steaming, grill the tomatoes on all sides until blackened and split.
- Cut tomatoes in half and remove the blackened skin and any seeds.
- Place tomato pieces in a blender.
- Remove pepper from the bag, then peel or scrape off the blackened skin, remove ribs and seeds. Place pepper in the blender.
- Add ají amarillo, nut paste, olive oil, lime, and salt. Purée until smooth and light in color, transfer to a bowl and set aside.
To Cook the Fish:
- Trim the fish into equal 6-ounce portions and place in a shallow baking dish.
- Finely chop the basil, thyme, and lavender buds together and place in a small bowl.
- Add the salt, pepper, and olive oil. Spoon over the fish, turn to coat, and marinate for 20 minutes.
- Meanwhile, preheat grill to medium-high - about 400°F/200°C.
- When hot, oil the grates then grill fish for 4 minutes on the first side and three minutes on the flip side. (You will see the fish becoming opaque as it cooks.)
- Spoon a couple of tablespoons of the sauce onto the plates, then top with fish and garnish with chopped parsley.
Notes
* Chilean sea bass is technically not a Bass but a cold-water fish called the Patagonian toothfish. A good substitute is sablefish, also known as black cod (lieu noir).
