Pasteis de coco (portuguese coconut-custard tarts)

2 tablespoons cornstarch
1 cup milk
1 cup flaked coconut
3 large eggs
1 cup sugar
2 tablespoons unsalted butter, melted
1/4 teaspoon lemon extract

1. Preheat the oven to 375 F (190 C). Adjust the rack to middle position. Line a 12-cup muffin tin with 10 foil cupcake papers.
2. Dissolve the cornstarch in 1/4 cup of the milk. Set aside.
3. In a food processor fitted with a metal blade shred the coconut flakes for 30 seconds.
4. In a large mixing bowl, stir the eggs and sugar together with a wooden spoon. One by one, add the cornstarch mixture, remaining milk, coconut, melted butter and lemon extract, stirring well after each addition.
5. Ladle the custard into the paper cups, filling to 1/4 inch from the top.
6. Bake for 25 to 30 minutes or until the coconut is nicely toasted. Cool completely in the tin before serving.
