5ouncesfresh Genovese basil leaves(stems removed; see notes)
one large garlic clove(or two small)
2Tablespoonspine nuts(can omit if needed)
½cupolive oil
½cupfreshly grated Parmesan cheese
½cupfreshly grated imported Pecorino Romano cheese
Instructions
Rinse the basil and pluck off the stems. Pat the basil leaves with a paper towel to absorb excess water and place the leaves on paper towels to air-dry. (See notes.)
Grate the cheeses, if needed (I use my blender.) Combine the Parmesan and Romano in a small bowl.
Peel the garlic and place it in a food processor. Add the pine nuts. Pulse until the garlic is cut into small pieces.
Add the basil leaves to the food processor and pulse until they're broken up, while drizzling in the olive oil.
Add the combined cheeses to the food processor and process until a creamy paste is formed. There is no need for salt, since the cheese is salty enough.
Use the pesto as a sauce stirred into pasta or on pizza, chicken or fish. Store the pesto in a sealed container in the refrigerator, with a thin layer of olive oil on top, for up to two weeks. You also can freeze it for up to six months.

Notes
Genovese basil with corrugated leaves provides the best flavor, but you can use regular sweet basil instead.
The basil must be air-dried to ensure the leaves have no moisture, in order to achieve the right pesto texture.
If you don't have a scale to weigh the basil, you can fill up a 2-cup liquid measuring cup twice with packed basil until it's heaping.
Imported Pecorino Romano (made from sheep's milk) is key for flavor.
