Lynne's Linguine con Pesto di Pistacchi

1 . Stage

Heat a large heavy-bottomed skillet over medium heat. Pile in pistachios and pine nuts. Cook, stirring frequently, until light brown and incredibly nutty-smelling, 3 to 5 minutes. Transfer to a food processor.

2 . Stage

Add garlic to the skillet and cook, turning occasionally, until softened and browned in patches, about 5 minutes. Remove to a plate to cool.

3 . Stage

Peel cooled garlic and add to the food processor, along with basil, and process. With the blade still running, drizzle oil in through the chute. Once incorporated, transfer to a large bowl. Stir in salt, black pepper, and red pepper.

4 . Stage

Meanwhile, bring a large pot of lightly salted water to a boil. Cook linguine at a boil until tender yet firm to the bite, about 11 minutes. Reserve about 3/4 cup pasta water. Drain remaining water from pasta and give the colander a good shake or two.

5 . Stage

Add pasta and tomatoes to pesto. Give it all a good mix and drizzle in enough of the reserved pasta water to get the nutty pesto to coat the pasta. Sprinkle with Parmigiano-Reggiano cheese.
