Preparation

• Position a rack in the center of the oven and heat the oven to 350°F.

  In a large bowl, toss the cherries and kirsch. Set aside, tossing periodically, for 30 minutes.

  Meanwhile, scatter the almonds on a baking sheet and toast, turning occasionally, until light golden, 3 to 4 minutes. Set aside. Increase the oven temperature to 400°F.

  Grease a shallow round 11-inch quiche or gratin dish with 1/2 Tbs. of the butter.

  Combine the milk, flour, sugar (1/4 cup for sweet cherries; 5 Tbs. for sour), cream, eggs, almond extract, and salt in a stand mixer fitted with the whisk attachment (or in a bowl, if using a hand mixer). Mix on medium speed, to aerate, for 5 minutes. Drain the cherries and stir the liquid into the batter.

  Arrange the cherries in the dish and pour the batter over the top. Bake for 15 minutes. Sprinkle the toasted almonds and remaining 1 Tbs. sugar on top and dot the surface with pieces of the remaining 1 Tbs. butter. Bake the clafoutis until puffed and golden-brown, and a toothpick inserted in the center comes out clean, 35 to 40 minutes.

  Transfer to a rack and let cool for 30 minutes. Serve warm or at room temperature, spooned onto individual serving plates.
