How to Make It
In a small frying pan, toast the pine nuts over moderately low heat, stirring frequently, until golden brown, about 5 minutes. Or toast them in a 350° oven for 5 to 10 minutes.
Combine the raisins and the boiling water. Let stand until plump, about 10 minutes. Drain.
In a large frying pan, heat the oil over moderately low heat. Add the garlic and cook, stirring, for 1 minute. Stir in the spinach and cook, stirring, until just wilted, about 2 minutes.
In a large pot of boiling, salted water, cook the farfalle until just done, about 15 minutes. Drain. Toss with the pine nuts, raisins, spinach mixture, prosciutto, salt, pepper, and Parmesan.
Replace the pine nuts with walnuts.
Substitute Swiss chard for the spinach.
