Pesto Marinade

A dense, herbaceous, aromatic cold Genoese pesto marinade, made in a mortar to coat meat, fish, or vegetables before resting in the refrigerator.

Ingredients

  • 80 g fresh Genovese basil, in a bunch
  • 160 ml mild Italian extra-virgin olive oil
  • 40 g shelled pine nuts
  • 50 g aged Parmigiano Reggiano
  • 25 g aged Sardinian pecorino
  • 2 cloves fresh garlic
  • 1 tsp coarse sea salt
  • 1 pinch whole black peppercorns

Method

  1. Rinse the basil very briefly under cold water, then spread it on a clean cloth. Dry it carefully, without crushing it, until the leaves no longer glisten with moisture.
  2. Pull the basil leaves from the stems and discard the large, fibrous stalks. Keep the small tender stems if they are fragrant and supple between your fingers.
  3. Put the garlic and coarse salt in a mortar. Crush with the pestle in a circular motion until you have a smooth, wet, intensely fragrant paste with no visible pieces of garlic.
  4. Add the pine nuts. Work them against the side of the mortar until they become creamy and begin to bind the garlic paste.
  5. Add the basil in small handfuls. Grind with a turning motion, without striking hard, until the leaves break down, darken slightly, and release a clear fresh-basil aroma.
  6. Add the grated cheeses. Mix with the pestle until you have a thick, grainy, homogeneous paste that sits on the spoon.
  7. Pour in the olive oil gradually in a thin stream while continuing to turn the pestle. The marinade should become glossy, supple, and coating, thick enough to cover the back of a spoon without running like a vinaigrette.
  8. Add freshly ground black pepper and taste. The marinade should be distinctly salty, aromatic, and slightly hot, since it will season the food during the rest.
  9. To use it as a traditional marinade, coat the chosen food in a nonreactive dish, cover it directly, and refrigerate overnight and through the following day. Turn the food halfway through so the coating remains even.
  10. Before cooking the marinated food, remove excess marinade from the surface to keep the basil and cheese from burning. Cook according to the food, then optionally add a small spoonful of fresh marinade off the heat to revive the aroma.
