Pesto Genovese is the classic basil sauce of Liguria. Its modern form was documented in Genoa in 1865; older Roman herb-and-cheese sauces are considered possible antecedents, not a proven direct origin.
Fresh basil gives this sauce its fragrant, vibrant flavor. Pine nuts and two aged cheeses add richness and savory depth. It’s delicious with trofie, trenette, gnocchi, or vegetables.
Tips
Dry the basil completely to help keep the pesto bright.
Use a gentle grinding motion instead of pounding the leaves hard.
Refrigerate leftovers under a thin layer of olive oil and use within a few days.
