Anchovy Dressing with Capers

This is for anchovy lovers-and we are, so we make a lot. Don't be tempted to halve the recipe: Mashing anchovies takes time and, anyway, there are any number of wonderful ways to use this. Besides salads, spoon it over boiled potatoes, roasted vegetables, steak or roast beef sandwiches, croutons (before you toast them), or reheated pizza.
