in the kitchen: pasta al pesto

Slow food maven Alice Waters’ Pasta al Pesto, from The Art of Simple Food, is quite easy and absolutely delicious. I substitute Romano for half of the Parmesan, for a little extra kick. (Full disclosure: I also substitute a food processor for the mortar and pestle… Don’t tell Alice.)
Pesto:
Pick the leaves from 1 bunch of basil, to yield about 1 lightly packed cup
In a mortar and pestle, pound to a paste:
1 garlic clove, peeled
Salt
Add and continue to pound:
1/4 cup pine nutes, lightly toasted
Add:
1/4 cup grated Parmesan cheese
Transfer this mixture to a bowl. Coarsely chop the basil leaves and put them in the mortar. Pound the leaves and pine nut mixture together. Continue pounding as you gradually pour in:
1/2 cup extra-virgin olive oil
Taste for salt and adjust if necessary.
Pasta:
Cook in abundant salted boiling water:
3/4 pound dry pasta (linguine, spaghettini, fedelini, trofie)
Cook al dente. Drain, reserving 1 cup of the cooking water.
Return the pasta to the pot or place in a large warm bowl and toss with:
1 1/2 cups Pesto
Salt
Mix about 1/2 cup of the reserved hot pasta water into the noodles. Taste and add more salt or water if needed. Plate and garnish with:
Freshly grated Parmesan cheese
Serve immediately.
