½ cup raisins
Red wine vinegar
Kosher salt and freshly ground black pepper
8 ounces spaghetti
Extra-virgin olive oil
2 garlic cloves, thinly sliced
½ cup pine nuts
½ teaspoon dried chile flakes
1 bunch Swiss chard, dried ends trimmed, stems thinly sliced, leaves torn into strips
3 tablespoons unsalted butter
Parmigiano-Reggiano cheese, for grating
- Combine the raisins, a splash of vinegar, and warm water just to cover in a bole and plump for 20 minutes. Drain.
- Bring a large pot of water to a boil and add salt until it tastes like the sea. Add the spaghetti and cook according to the package directions. Start tasting a minute or so ahead of time so you don’t overcook it. With a ladle or a measuring cup, scoop out about ½ cup of the cooking water, and drain the pasta well.
- Meanwhile, pour a healthy glug of olive oil into a large skillet over medium-low heat. Add the garlic and pine nuts and let them toast very slowly until lightly browned, about 5 minutes. Add the chili flakes and cook for another 10 seconds so they can bloom, then add the drained raisins.
- Increase the heat to medium, add the chard stems, season with a bit of salt and black pepper, and cook slowly until the stems are slightly tender, 3-4 minutes. Add the torn chard leaves and splash of water (use the pasta water, needed), cover the pan, and cook until the leaves are wilted, 2-3 minutes.
- Add the drained pasta the butter to the chard and toss well. Taste and adjust the seasoning with more salt, black pepper, or chile flakes. Grate a bit of Parmigiano over everything, drizzle with more olive oil and pile into bowls. Serve with more cheese.
