Pan-Seared Halibut With Olive Oil Potatoes

Preparation

1. Step 1

   Place potatoes in a large pot and cover with lightly salted water. Bring to a boil and cook until tender when pierced with a knife. Meanwhile, in a small skillet, combine 1 tablespoon olive oil and ½ clove sliced garlic. Sauté over low heat until lightly golden, then add anchovy and ¼ teaspoon thyme leaves. Transfer to a small food processor and add olives, 1 tablespoon olive oil and 1 teaspoon cold water. Purée until smooth and season to taste with white pepper; set aside.

2. Step 2

   When potatoes are tender, drain and put through a food mill or mash them. Return to pot and place over low heat. Stir with a wooden spoon until potatoes start to stick to pot, then slowly add milk, 2 tablespoons olive oil and ½ pound butter. Stir until very smooth, then season to taste with salt and pepper. Set aside and keep warm.

3. Step 3

   In a medium saucepan, combine remaining 2 tablespoons olive oil with 3 cloves sliced garlic. Sauté over medium heat until garlic is aromatic. Add shallot and sauté until translucent. Stir in peppers, 1 teaspoon salt and sugar. Reduce heat to low, cover and cook for 2 minutes. Add chicken stock and saffron; simmer, partially covered, until peppers are tender, about 8 minutes. Purée in a food processor, blender or with an immersion blender, and pass through a fine sieve. Transfer to a small pan and season with cayenne and salt to taste. Add 2 tablespoons butter and whisk or blend until frothy. Set aside and keep warm.

4. Step 4

   Heat oven to 350 degrees. Season halibut fillets with salt and pepper to taste. Place a large ovenproof skillet over medium-high heat and add grapeseed oil. When oil is hot, add fillets presentation-side down. Cook for 1 minute on stove top, then place in oven for 5 minutes. Remove pan from oven and return to stove top on medium heat. Add remaining 1½ tablespoons butter to pan. When it starts to foam, add remaining 2 cloves garlic and sprigs of thyme. Baste fish with butter for 1 minute. Remove fillets from pan when undersides are golden brown.

5. Step 5

   To serve, place a large spoonful of potatoes in middle of four wide-rimmed plates or shallow soup bowls. Top with a halibut fillet, seared-side up. Place a spoonful of olive mixture on each fillet. Bring bell pepper emulsion to a boil and whisk until foamy, then pour around potatoes.
