1 thick slice country bread, crust removed
2 tablespoons aged red vine vinegar
1 clove garlic, coarsely chopped
1/2 teaspoon fine grain sea salt
1/3 cup / 1/4 oz / 8 g marjoram leaves
3 tablespoons capers, rinsed
1/2 cups / 1 1/2 oz / 45 g pine nuts or walnuts
1 cup / 1 1/4 oz / 35 g finely chopped parsley
10 pitted green olives
1/2 cup / 120 ml olive oil
Place the bread on a plate and sprinkle the vinegar over it. Pound the garlic with the salt in a mortar until smooth, then, one at a time, work in the marjoram, capers, nuts, parsley, and olives. Pound until the mixture has the texture of a coarse puree. Add the bread, then the olive oil and work all the ingredients together until the sauce comes together. Season with pepper, then taste for vinegar and salt, adding the smallest bit more if needed. If you like a looser sauce, thin with a bit more oil. It will keep refrigerated for a few days.
Makes about 1 cup.
Serve with pasta, worked into egg or potato salad, spread on bruschetta or sandwiches, or tossed with roasted or sauteed vegetables.
