How to Make It
Place the currants in a small microwavable bowl; cover with 2 tablespoons of water. Microwave on high for 1 minute, then drain. Transfer the currants to a mini food processor, add the pine nuts and anchovy and pulse to a paste.
In a large skillet, melt 2 tablespoons of butter. Add the cauliflower and cook over moderate heat, stirring once, until golden in spots, about 7 minutes. Add the stock and season with salt and pepper. Cover and cook until the cauliflower is nearly tender, about 3 minutes. Uncover and cook until the liquid is nearly evaporated and the cauliflower is tender, about 2 minutes longer.
Meanwhile, in a small skillet, heat 1 tablespoon of the butter. Add the bread crumbs and toast, stirring frequently, until golden, about 2 minutes. Transfer to a plate. Melt the remaining 2 tablespoons of the butter in the same skillet. Add the onion and garlic and cook over moderately low heat, stirring occasionally, until softened, about 5 minutes. Add the wine. Stir in the currant paste and transfer to a bowl.
Transfer the cauliflower to a bowl. Stir the bread crumbs into the currant mixture, spoon over the cauliflower and serve at once.
