Preheat the oven to 375°F.
Smear a 2-quart shallow baking dish liberally with butter.
Stem and pit cherries. Lay in a single layer in the baking dish.
In a standard blender, or using an immersion blender and a bowl, mix eggs, flour, salt, vanilla, lemon zest, almond extract, ½ cup sugar, and cream together until smooth.
Pour batter over cherries. Sprinkle with 3 tablespoons of sugar and dot with butter.
Bake the clafoutis at 375°F for about 45 minutes, until the custard is just set; a knife poked in the center should emerge relatively clean.
Allow to cool and sprinkle with confectioner’s sugar before serving. Serve with vanilla ice cream or softly whipped cream.
MAKE IT NON-DAIRY: Substitute almond milk for heavy cream and extra virgin olive oil for butter.
