Bacon-Balsamic Vinaigrette

In a medium skillet, toast the pine nuts over moderate heat until browned, about 3 minutes. Transfer to a plate to cool.

Add the bacon to the skillet, cover with cold water and add 1 teaspoon of salt. Bring to a boil, then drain and pat dry.

Heat the olive oil in the skillet. Add the bacon and cook until crisp. Transfer the bacon to a plate. Whisk the vinegar into the fat in the skillet and season with salt and pepper. Add the pine nuts and bacon just before serving the dressing hot or warm.
