You can easily change the flavor of pesto by changing the herb that you use or the nuts. You can even change both as this recipe shows. This pesto is great as a marinade for meat or drizzled over meat after cooking.
1 cup fresh Rosemary, stripped from stems
2 or 3 cloves Garlic
1 tablespoon fresh Orange Zest
1/3 cup toasted Walnuts
1/2 cup Extra-Virgin Olive Oil
1/2 cup Parmigiano-Reggiano cheese, freshly shredded or grated
Salt and Pepper to taste
Place rosemary, garlic, zest and walnuts into a food processor and pulse to chop coarsely. With the machine running, slowly stream the olive oil, forming a loose sauce. For immediate use, add cheese and pulse a few more times to combine. Add salt and pepper to taste.
