Butter a 10x10 square pan and add the pears in an even layer. Pulse the almonds in the work bowl of a food processor until they resemble a fine cornmeal. Add the rest of the ingredients and pulse to combine. Pour the batter evenly over the pears and place into the oven. Bake for about 20 minutes or until the clafouti is puffed, browned and beginning to pull always from the sides. Check after ten minutes and rotate pan for even browning. Serve warm or at room temperature.
