I start by heating the milk until steaming but not boiling. In a bowl, I whisk egg yolks, sugar, cornstarch, and salt until smooth. The hot milk is slowly added to temper the eggs, then everything goes back on the stove and cooks until thick. Once off the heat, I stir in passionfruit purée and butter, then chill it completely.
Water, butter, and salt are brought to a boil in a saucepan. I add the flour all at once and stir until a smooth dough forms and pulls away from the sides. After cooling slightly, the dough goes into a mixer and eggs are added one at a time until glossy and pipeable.
Soft butter and brown sugar are mixed together until creamy. I add green food coloring, then flour to form a dough. It’s rolled thin between parchment paper and chilled until firm, making it easy to cut neat circles.
I pipe small rounds of choux dough onto parchment-lined baking sheets. Frozen craquelin discs are placed on top of each mound. The puffs bake until tall, golden, and crisp, then cool completely before filling.
Whipping cream is beaten until stiff peaks form, then gently folded into the chilled passionfruit cream. I fill each puff from the bottom and finish with a swirl on top. A light dusting of gold luster dust gives them their fairy-inspired finish.
