How to Make It
In a small skillet, heat the olive oil until shimmering. Add the capers and fry over high heat, stirring occasionally, until browned and shriveled, about 4 minutes. Strain the capers and discard the oil.
Cook the spaghetti in a large pot of boiling salted water until al dente. Meanwhile, in a mortar or mini-processor, combine the anchovies, garlic and lemon zest; pound or process to a thick paste. Transfer to a large bowl and stir in the parsley, extra-virgin olive oil, lemon juice, crushed red pepper and fried capers.
Drain the spaghetti. Add it to the fried caper mixture, toss to coat and serve.
