An addictive melange of spinach, garlic, raisins, pine nuts and good olive oil, this is one of the best Catalan dishes. Its uses in the Catalan kitchen are many - in croquettes or egg tortillas, as a topping for cocas (flat breads), as a filling for savory turnovers or cannelloni, or as a base for baked fish. As a side dish, it goes with just about anything, and nothing beats it in the morning on toast, topped with poached eggs. The recipe is also great made with other wilted greens, such as chard or escarole. Adapted from "The New Spanish Table" cookbook.
