I found this recipe on a wonderful blog, CafeFernando.com. The creator credits Dorie Greenspan for the crust and Martha Stewart for inspiring the filling.
To make the crust, pulse flour, sugar and salt in a food processor. Add butter and pulse until it resembles a coarse meal. Stir in the yolk and pulse again until the dough forms clumps and curds.
3
Turn the dough out onto a work surface and very lightly and sparingly, knead just to incorporate dry ingredients.
4
Butter a 9-inch fluted tart pan with a removable bottom. Press the dough evenly over the bottom and up the sides of the pan. Freeze crust at least 30 minutes before baking.
5
Bake blind for 15 minutes, remove the weight and let cool.
6
For the filling, pulse almonds, sugar and salt in a food processor. Add butter and the whole egg and process until the mixture is smooth.
7
Spread the mixture on the partially baked tart dough. Smooth the top and place the sour cherries.
8
Reduce the temperature to 350° F and bake for another 25 minutes, or until crust is golden brown and filling is just beginning to brown around the edges. Serve warm.
