Tart cranberries are paired with Gorgonzola, that piquant Italian blue cheese, for a happy marriage and a delicious recipe. To make ½ cup walnut meal, place ¾ cup walnut halves or pieces in a food processor and pulse until ground, making sure not to overprocess into a paste.
Heat oven to 300º.
In the bowl of a food processor, combine flour, walnut meal, ⅓ cup sugar, salt, and sage. Pulse to incorporate. Add butter. Pulse to form a coarse meal, 30 seconds.
With your fingers, press meal into an ungreased 10-inch springform pan.
Bake until light golden-brown, about 55 minutes. Cool completely and release from springform pan.
In a small saucepan over medium-low heat, cook cherry preserves until melted. Add cranberries, remaining ⅓ cup sugar, and cherry liqueur. Simmer, stirring occasionally, until cranberries have lost their shape, about 25 minutes. Remove from heat and cool completely, about 1 hour.
Crumble Gorgonzola over tart crust in an even layer. Top with a thin layer of cranberry mixture. Divide into 10 even slices and serve.
