Put the basil, garlic, and walnuts in a food processor fitted with a steel blade and chop. (The book says it can possibly be made in a blender, too, but use 1/2 the recipe.)

Add the olive oil in a slow steady stream while the motor is running.

Shut off motor; add cheeses, a pinch of salt, and liberal grinding of black pepper. Process briefly (say 30 seconds or so) and scrape out into a bowl. Keep covered or it will oxidize.

This recipe is modified from The Silver Palate, my favorite cookbook. All I did was crank up the garlic :).
