Look for wild garlic and lamb's-quarter at your local farmers market in the spring and summer.
3 to 4
wild garlic cloves or 1 small regular clove, chopped (1 teaspoon)
loosely packed lamb's-quater leaves (sometimes called wild spinach or fat hen), washed and dried
finely grated Parmigiano-Reggiano (1/3 cup)
extra-virgin olive oil
Put oven rack in middle position and preheat oven to 350ºF.
Toast nuts in a shallow baking pan in oven, stirring once or twice, until pale golden, about 10 minutes.
Mince chopped garlic and mash to a paste with salt using side of a large heavy knife, then transfer to a food processor. Add lamb's-quarter and pulse until finely chopped. Add cheese and toasted nuts and process until nuts are finely chopped. With motor running, add oil in a thin stream through feed tube.
- For pasta with pesto: Put 2/3 cup pesto in a large bowl and cook 1 pound pasta until al dente, then whisk about 1/3 cup pasta cooking water into pesto. Add drained pasta to thinned pesto with salt and pepper to taste and toss well. Serve with additional grated Parmigiano-Reggiano.
- Pesto keeps, frozen in an airtight container, 3 months.
