The key here is keeping the cooking liquid (in this case, oil) at a low temperature. It should never rise above boiling (212°F).
Olive Oil-Poached Salmon
4 cups water
1/4 cup kosher salt
4 skinless, center-cut salmon fillets (6 oz each)
1 clove garlic, smashed
3 cups extra-virgin olive oil
1. Whisk water and salt in a large bowl. Add fillets and soak for 4 minutes. Remove and pat dry.
2. Peel lemon into 1-inch strips. Rub a shallow skillet with lemon peel (skin side) and garlic, and leave both in the pan.
3. Fill the skillet with enough oil to cover fillets. Heat on medium until a food thermometer reads about 125°F. Add fillets and cook until their internal temperature reaches 115°F to 145°F, about 10 to 12 minutes. (Adjust heat as needed to keep the oil temperature around 125°F.)
4. Remove fillets to a wire rack to drain. Serve with lemon wedges and greens.
