Step 1Place currants in small bowl, cover with wine and set aside to plump, about 10 minutes.
Step 2Bring large pot salted water to boil for pasta. Cook pasta until al dente, 10 to 15 minutes.
Step 3While pasta is cooking, heat large skillet over medium heat. Add pine nuts and toast, stirring frequently until lightly browned, about 3 minutes. Set aside on plate.

Add currants, wine, capers, anchovies, red pepper flakes and parsley. Simmer 2 minutes, add salt and pepper to taste, then remove from heat.
