The most basic, most traditional pesto is this basil-based one that was invented in Genoa, in northern Italy; it's bright green and wonderfully aromatic. Be sure to add your oil slowly, so that the sauce fully emulsifies - that is, all the ingredients bind together, creating a thick, uniform consistency.

Lots of basil varieties are available, some sweeter, some spicier, and in fact basil is an important ingredient in the cooking of southeast Asia, especially in curries. Each variety will impart its unique flavor to a pesto, so be adventurous, and try whatever type appeals to you. Just remember: you need a lot of it, and it should be fresh and crisp, not wilted or soggy.

Giada's Classic Pesto

The secret to making pesto into a great pasta dressing is to get the sauce to the right consistency. Fresh from the food processor, pestos are usually too thick to coat pastas; you'll just end up with mounds of the sauce amid a lot of undressed noodles. You need to mix in just enough of the pasta cooking liquid to coat the pasta, but not so much that you've created pesto soup.

Ingredients

Instructions

  1. In a blender or food processor, pulse the basil, pine nuts, garlic, 1/2 teaspoon of salt, and 1/4 teaspoon of pepper until finely chopped. With the blender still running, gradually add enough oil to form a smooth and thick consistency. Transfer the pesto to a medium bowl and stir in the cheese. Season the pesto with more salt and pepper to taste.
  2. The pesto can be made 2 days ahead. Cover and refrigerate.
