How to Make It
Drape a kitchen towel over a small saucepan, and set a small metal bowl over it. Mash garlic and salt together in bowl; whisk in yolks and 2 tsp. warm water. Add oil, 1 tsp. at a time, whisking constantly. Add extra virgin olive oil in a slow, steady stream, whisking constantly. (If mixture gets too stiff, add more water.) Stir in lemon juice and pepper to taste. Serve with shrimp, eggs, and vegetables.
