Heat oven to 400° F. Cook the pasta according to the package directions. Drain the pasta and return it to the pot.

Meanwhile, spread the pine nuts on a rimmed baking sheet. Toast, tossing occasionally, until golden, 5 to 6 minutes.

Heat the oil in a medium saucepan over medium heat. Add the garlic and cook, stirring, until golden, 2 to 3 minutes. Add the tomatoes, raisins, 1/2 teaspoon salt, and 1/4 teaspoon pepper. Simmer until slightly thickened, 8 to 10 minutes. Stir in the capers.

Toss the pasta with the tomato mixture and pine nuts before serving.
