Capturing the heart and soul of the Côte d'Azur is Socca, the famous rustic chickpea flatbread that's embraced as Nice's original street food. This Socca recipe will transport you back to Provencal France from your very own kitchen!
In a mixing bowl whisk together the garbanzo bean flour, salt and pepper. Pour in the water and continue to whisk until the batter is smooth. Add 1 1/2 tablespoons olive oil and whisk to combine. Let sit at room temperature for at least 20 minutes or up to several hours.
Preheat the oven to 450 F.Heat a 12-inch heavy oven-proof frying pan (I prefer cast iron) and add the remaining 2 tablespoons of olive oil (I like to replace some of the olive oil with duck fat for the best flavor). Cook the onion until deeply caramelized, adding a small pinch of sugar to enhance the caramelization. Add the chopped rosemary and cook for another minute. Spread the onion mixture out evenly over the bottom of the pan.Pour the chickpea batter over the onion mixture. Place the pan on the middle rack of the oven and bake for 10-15 minutes or until the socca is firm, the edges are set, and it is golden in color. Next brush the socca with some additional olive oil and then place it under the broiler for another minute or two until well browned and just beginning to scorch in a few places.Cut into wedges and serve immediately while hot.
