1/4 cup lightly packed fresh tarragon leaves (about 1/4 ounce) OR 2 tablespoons dried tarragon
2 tablespoons olive oil
Juice of 1 lemon (about 1/4 cup)
1/4 teaspoon salt
1/4 cup water
Instructions
Place frozen peas in a medium saucepan. Add water to cover and bring just to a boil over medium high heat (10 to 15 minutes). Drain.
In the bowl of a food processor fitted with the metal blade, place peas, pistachios, tarragon, oil, lemon juice, and salt—all ingredients except water. Process until pistachios are finely ground. Add the 1/4 cup water and process until blended.
