I've been making pesto forever and have never been able to keep it bright green. It has such promise, such flavor, and I know that the pasta or whatever else I use it in will taste wonderful. But I've always been frustrated by how quickly the basil oxidizes and the color goes from bright green to drab. So I decided to try blanching the leaves very briefly to see if that would solve the problem and voilà! It did. You need to blanch the basil for only five seconds, and you don't want to blanch it for more than 10. Doing this leaches out a wee bit of the basil's vivid flavor, but not enough to change that of the pesto significantly. The texture and color are wonderful, and the pesto will keep for several days in the refrigerator (but it's best to wait until you're ready to use the pesto before adding the garlic and cheese).
