LEMON PESTO SAUCE RECIPES

Steps:

• Pulse pine nuts in a food processor until they're completely broken down. Stop to scrape down the sides of the bowl with a spatula from time to time. Add olive oil and garlic and pulse until garlic is finely chopped.
• Chop basil very roughly — just run a knife through it once or twice to cut most of the leaves into halves or thirds — then add to food processor. Pulse, stopping every 15 seconds to push the leaves down with a rubber spatula, until basil is entirely worked into the oil. Pulse for another few seconds, and then stop to prevent turning the basil brown.
• Pour pesto base into a bowl and add grated cheese and salt. Stir to combine, then taste and adjust seasoning as needed. Leave the sauce thick to toss with cooked pasta and a little pasta cooking water. To use the pesto as a garnish for grilled or roasted meats, fish and vegetables, thin it out with 2 to 3 more tablespoons olive oil until it’s the consistency of a loose paste. To store leftovers, pour a little more olive oil over the pesto to cover. Refrigerate in an airtight container for up to three days.

Steps:

• Light the grill or heat the broiler. In a small glass or stainless-steel bowl, mash the capers with a fork. Stir in the lemon juice, parsley, 1/2 teaspoon of the salt, and 1/4 teaspoon of the pepper and then 6 tablespoons of the oil.
• Coat the tuna with the remaining 2 tablespoons oil. Sprinkle with the remaining 1/4 teaspoon each salt and pepper. Grill or broil the tuna for 4 minutes. Turn and cook until done to your taste, 3 to 4 minutes longer for medium rare. Serve the tuna topped with the sauce.
