Ingredients

• 1 (1/4 ounce) package active dry yeast
• 3/4 cup water (110 degrees F.)
• 1/2 teaspoon sugar
• 1 tablespoon olive oil
• 1 3/4 cups flour
• 3/4 teaspoon salt
• 3 tablespoons additional flour, for kneading
• 2 lbs yellow onions, peeled, and very thinly sliced to yield 8 cups (about 5)
• 1/4 cup olive oil
• 1 tablespoon butter
• 3 garlic cloves, peeled and minced
• 1 teaspoon kosher salt
• 1/3 cup water
• 1 sprig fresh thyme (or 1/4 teaspoon dried)
• 1/4 cup freshly grated parmesan cheese
• 2 dozen flat anchovy fillets, oil drained, about
• 3 dozen oil-cured black olives, pitted
• 1/2 teaspoon fresh ground pepper

Instructions

1. Electric mixer method: In a large mixing bowl, sprinkle yeast over water with the sugar.

2. Let proof and soften for about 5 minutes.

3. With paddle attachment, add oil, and stir to blend.

4. Add 1 cup flour and stir until smooth.

5. With dough hook attachment, add remaining 3/4 cup flour and salt and knead until silky smooth and elastic, about 5 minutes.

6. Food processor method: Place flour and salt in food processor bowl; process briefly just to blend.

7. Combine oil and yeast mixture, pour down feed tube and process just until mixture is a lumpy mass.

8. Place this mixture on a lightly floured work surface and knead sticky dough for about 5 minutes until satiny and smooth.

9. Knead in no more than three tablespoons additional flour.

10. Place dough in large bowl, cover and let rise in a warm place away from drafts until doubled in bulk, about 1 hour.

11. While dough is rising, prepare the filling.

12. Heat the oil and butter in a large skillet and over medium-low heat sauté the onions, garlic and salt until soft and transparent, about 10 to 15 minutes.

13. Throughout the cooking time, always stir occasionally to prevent onions from browning or scorching.

14. Add the water and thyme, and over high heat cook until the water evaporates.

15. Over low heat, continue sautéing about 20 minutes longer, until onion mixture is similar to a paste (yield at this time is 3 cups).

16. Remove sprig of thyme.

17. Set aside to cool.

18. Adjust the rack in the lower third of the oven and preheat the oven to 425 degrees.

19. Rub 1 tablespoon olive oil over the bottom of a 10 x 15 jelly roll pan or a 12-inch pizza pan.

20. Punch dough down.

21. With fingertips, press and stretch the dough to fit the pan.

22. If the dough becomes elastic, rest a couple of minutes, then press again.

23. Cover dough loosely with plastic wrap and let rest about 30 minutes or until puffy.

24. Spread the onion filling evenly over the dough to the edges.

25. Sprinkle Parmesan over filling.

26. Arrange the anchovy fillets, lattice-fashion, over the filling and dot the olives over the surface.

27. Keep the design close together so that when cut, each portion will include an olive and some anchovy.

28. Bake for about 30 minutes or until edge of crust is light gold.

29. Sprinkle freshly ground pepper over top.

30. Cut rectangles, squares or wedges while warm or at room temperature.

31. Notes: For an extra crisp crust, spread filling over dough, and rather than allow time for the dough to rise and become puffy, bake it right away.

32. For a more bread-like crust, let dough rise in baking pan until puffy, then spread filling on top and bake.

33. If anchovy fillets taste too salty, rinse them in cold water and dry thoroughly with paper towels.
