Basil Pesto

Put the basil, garlic, salt and 2 or 3 grinds of pepper in a food processor and process until the basil and garlic are finely chopped, about 15 seconds.

With the machine runing, pour 1/4 cup of the olive oil down the feed tube in a slow, steady stream.

Turn off the processor and add the Parmigiano.

Process until the cheese is incorporated, about 20 seconds.

With the machine running, slowly add the remaining 1/4 cup oil.

Add the nuts and pulse until they're coarsely chopped.
