Pesto!

Mmm, pesto makes me endlessly happy. Growing up, we used fresh basil grown in the backyard. The stuff we bought at the store worked almost as well.

You'll need a food processor for this one. A blender will work, too.

Fresh basil leaves (2-4 oz)
Garlic (2-3 cloves) (note that this makes a VERY garlicky sauce)
Olive oil (1/2 cup)
Parmesan cheese (1/2 cup grated)
Salt to taste
Pasta - something with ripples or ridges to hold the sauce (1 pound)

Put the garlic in the food processor first. Chop it up and scrape it off the sides as needed. Next, add the basil and do the same. Add the olive oil a 1/4 cup at a time - grind it up until it starts to make a paste, scraping off the sides as needed. Add salt as desired. This will be pretty potent.

Put the paste into a small bowl and mix it with the parmesan. Pour it over the pasta and mix it until all the pasta is coated. Serve with more parmesan cheese as needed.
