Spanish Coca With Wilted Greens, Walnuts And Raisins

Instructions

1. In a bowl, dissolve the yeast in 2 tablespoons warm water. Let stand 10 minutes until frothy. Add the flour, salt, 1 cup warm water and 4 tablespoons olive oil. Knead on a floured surface until smooth, elastic and slightly tacky to the touch, about 7 to 10 minutes. Place the dough in an oiled bowl and turn it over so that it is completely coated with oil. Cover with plastic wrap and place in a warm place about 75°F. Allow to rise until double in volume, about 1 to 1½ hours.
2. Preheat oven to 375°F. Pour 1 cup boiling water over all the raisins and let stand 15 minutes. Drain. Place the walnut halves on a baking sheet and toast until fragrant and lightly golden about 7 minutes.
3. Remove the stems from the Swiss chard, wash, and spin the leaves dry. Warm two tablespoons of the olive oil in a frying pan over medium high heat, add the garlic and stir for 5 seconds. Add the Swiss chard and raisins and cook, tossing occasionally with tongs, until wilted, about 6 to 8 minutes. Season well with salt and pepper.Place a pizza stone on the bottom shelf of the oven and increase the oven temperature to 500°F.
4. Punch down dough and cut into 2 pieces. Flour surface and roll one piece of the dough into a long, flat oval shape, about ⅜” thick, 8” x 10”. Build up edges slightly. Place the dough on a well-floured pizza peel or paddle. Place half of the greens on the dough, distribute evenly, leaving a half inch border around the edge. Top with the walnuts and drizzle with the remaining 2 tablespoons olive oil. Bake until golden and crispy, approximately 15 to 18 minutes. 
5. Remove coca from pan and cut into wedges. Serve immediately or at room temperature.
