"Just to clarify, there are no tangerines in this dessert, nor does it look like a pie! Kuey tarts translates to pineapple tarts. In Singapore, this is a highly-prized gift for Chinese New Year. Traditionally, people give away fresh tangerines, a homonym for “gold” in Chinese. When Western-style baked goods were introduced, this round turnover was created to resemble the real thing, with its crackly orange egg yolk wash and clever little clove garnish on top.
Some tips: Don’t eat the clove! It is only a decorative touch and will definitely ruin your tasting experience. And be sure to roll the dough thinly. The dough’s primary purpose is to encase the filling."
For the pineapple filling: Put all of the ingredients for the filling into a medium saucepan and
set over low heat. Cook, stirring, until the sugar has melted and the juice has thickened, about 45 minutes. When the mixture is very thick and there is no liquid at the bottom, transfer to a bowl, cover, and refrigerate overnight.
Place the butter, confectioners’ sugar, salt, whole egg, and egg yolk in the bowl of an electric stand mixer fitted with the paddle attachment. Cream together ingredients on medium speed until fluffy, scraping down the sides of the bowl. Sift the flour and milk powder into the bowl. Mix on low speed just until the dough comes together. Transfer the dough to a large piece of plastic wrap, wrap tightly, and refrigerate overnight.
Preheat oven to 350° F and line a baking sheet with parchment paper. Unwrap the chilled dough and transfer to a lightly floured work surface. Dust the dough with flour and roll to 1/8-inch thickness, rotating and flouring occasionally to prevent sticking. Use a floured 3-inch round biscuit cutter to cut out 8 circles.
Spoon 1 tablespoon of the pineapple filling in the center of each circle. Fold the dough circle in half and pinch the edges together to seal. Turn the package over so that the seam faces down and flatten slightly into a tangerine-like shape. Repeat with the remaining dough circles. Transfer to the baking sheet, setting pastries 2 inches apart. Brush with the beaten egg yolks, and stick a clove in the center of each package. Bake until golden brown, with a slight crack, about 15 to 18 minutes. Cool and serve. The pastries may be kept for two weeks in an airtight container.
