How to Make It
Preheat the oven to 350°. In a saucepan, simmer the cranberries with 1/4 cup of the sugar, the cloves and water over moderately low heat until the berries pop and the liquid thickens, about 8 minutes. Transfer to a blender and puree until smooth. Strain and press the puree through a fine sieve set over a bowl and let cool completely.
In a medium bowl, whisk the remaining 2 1/2 cups of sugar with the eggs, egg yolks, lemon zest, lemon juice and flour.
Mix 1 cup of the lemon filling into the cranberry puree; pour the rest of the lemon filling into the crust. Swirl in the cranberry-lemon mixture. Bake for 35 minutes, or until set. Transfer the pan to a rack; let cool. Dust with confectioners' sugar and serve.
