Pistachios, when eaten with high-carbohydrate foods, may result in lower than expected blood sugar levels, an important factor in reducing risk of diabetes.
2 egg yolks
3 garlic cloves, crushed
1 tablespoon mustard
½ teaspoon kosher salt
¼ teaspoon freshly ground black pepper
1/3 cup canola or vegetable oil
1/3 cup roasted pistachio kernels, coarsely chopped
1 teaspoon freshly squeezed lemon juice
½ cup + 2 tablespoons olive oil
1-1/2 cups diced onion
2 tablespoons chopped garlic
¼ teaspoon loosely packed saffron threads
2 large ripe tomatoes, prefereabley heirloom, cored and cut into large cubes
1 pound fresh halibut filet (divided into 4-oz portions)
To prepare the pistachio relish, combine egg yolks, garlic, mustard, salt and pepper in a small bowl using a wire whisk. Gradually add the oil, whisking vigorously in order to fully emulsify the ingredients. Add the pistachios and lemon juice and stir just until evenly combined. Set aside in a refrigerator.
For the tomato stew, heat a casserole or saucepan over medim-high heat until hot. Add the olive oil and as soon as it ripples, add the onion, garlic and saffron and cook, stirring occasionally for 3 to 4 minutes, or until the onion is translucent and just beginning to color. Stir in the tomatoes, cook for a few seconds and then cover and decrease the heat to low. Cook for 20 minutes to blend the flavors.
Just before serving, warm 2 tablespoons olive oil in a medium non-stick pan over medium heat. Sprinkle the filets with salt and pepper before adding them to the sauté pan. Sear the filets for approximately 2 minutes on each side or until cooked through and lightly browned. On a serving platter, lay a bed of the tomato stew, place the fish on top of the tomatoes and scoop the relish along on center of the filets. Serve immediately.
