Tomato and Almond Pesto

In Italy pesto can be more then basil, Parmesan, olive oil and pine nuts. This recipe from America's Test Kitchen was inspired by the various types of "red" pesto that must be discovered and loved by people on this side of the Atlantic. I LOVED this and Stew said he might even like it better then classic pesto. That's big. Try. Its so good!

Ingredients:

1/4 cup slivered almonds
12 oz cherry or grape tomatoes (about 2 1/2 cups)
1/2 cup packed fresh basil
1 medium garlic clove minced
1 small pepperoncini minced (can sub with 1/4 tsp of red pepper flakes and some vinegar)
table salt
pinch red pepper flakes
1/3 cup extra-virgin olive oil
1 pound pasta, preferably linguine or spaghetti
1 oz Parmesan cheese grated (about 1/2 cup)
plus extra for serving

Toast almonds in small skillet over med heat, stirring frequently until pale golden and fragrant (2 to 4 min). cool almonds to room temp. Add to blender (or processor): almonds, tomatoes, basil, garlic, pepperoncini, 1 tsp salt, and red pepper flakes and blend until smooth. With machine on low slowly drizzle in oil.
Meanwhile bring 4 quart water to a boil in large pot. Add pasta and 1 TB salt and cook until al dente. Reserve 1/2 cup cooking water, drain pasta and transfer back to cooking pot.
Add pesto and 1/2 cup Parmesan to cooked pasta and adjust consistency with reserved pasta cooking water so that pesto coasts pasta. Serve immediately, passing Parmesan separately.
