Sweet Corn and Blueberry Trifles

Make the pastry cream: Pulse dried corn kernels in a mini food processor until coarsely ground; set aside. Combine gelatin and ¼ cup cold water in a bowl and let sit until softened, about 5 minutes; set aside. Combine milk with corn husks and kernels in a 4-qt saucepan. Bring to a simmer over medium heat; remove from heat and steep 30 minutes. Remove and discard husks. Transfer milk mixture to a blender and puree until smooth. Strain milk mixture, discarding solids, and return to saucepan along with the dried corn kernels, and salt. Return to a simmer over medium heat. Whisk sugar and egg yolks in a bowl. Slowly whisk ½ cup hot milk mixture into egg mixture until smooth, then transfer egg mixture to saucepan. Cook, stirring constantly with a wooden spoon, until mixture is thick enough to coat the back of the spoon, 5-7 minutes. Remove from heat and add gelatin mixture, whisking until gelatin is dissolved. Strain custard through a fine strainer into a bowl, set over a larger bowl of ice water. Cover surface of custard directly with plastic wrap; refrigerate until cold. Beat cream to soft peaks and gently fold into custard; set aside.

Make the shortbread crumble: Heat oven to 325°. Pulse flour, corn kernels, corn flour, sugar, salt, and baking powder in a food processor until finely ground. Add butter and pulse into pea-size crumbles. Add egg yolk; pulse until shortbread mixture comes together. Spread on a parchment paper-lined baking sheet. Bake until golden brown, about 10 minutes. Let cool completely and break into bite-size pieces; set aside.

Assemble the trifles: Layer pastry cream and blueberry compote in small glasses or ramekins; top with shortbread crumble.
