Spiced Tomato Gratin...My Way
2 teaspoons curry powder
1/2 teaspoon red pepper flakes
1/4 cup extra-virgin olive oil
1 tablespoon unsalted butter
a small handful of basil leaves, slivered
Combine the spices in a small bowl and set aside.
You can get a jump start on the onions while you slice the potatoes and tomatoes. Heat half of the olive oil, 2 tablespoons, in your largest skillet or dutch oven over high heat. When hot, stir in the onions along with a few pinches of salt. Cook for a few minutes, stirring often, until the onions soften up - 4-5 minutes. Turn the heat down to medium and stir in the butter. Stirring regularly, cook another 10 - 15 minutes at this temperature, or until the onions just begin to caramelize a bit. Dial the heat back a shade more, and cook until the onions are deeply golden, this might take another 20 minutes. A minute before the onions are finished cooking
Smear half the caramelized onions across the bottom of a 10x10 inch (or equivalent) gratin or baking dish. Take half of the potatoes and half of the tomatoes and arrange on top of the onion layer (see photo). Drizzle with a couple tablespoons of cream from the potatoes and a tablespoon of olive oil. Season the layer with a pinch of salt and half the basil.
Scatter the remaining onions across the potatoes and tomatoes already in the pan. Then arrange another layer of tomatoes and potatoes on top. This will be the top of your gratin, so do your best to make it look nice. Pour the remaining cream, from the potatoes, and last tablespoon of olive oil across the top. Season with another pinch of salt and the remaining basil. Gently press down on the vegetables so the cream comes up through the layers of vegetables evenly.
Serves 10 as a side.
