A classic Hong Kong-style egg tart featuring flaky, golden puff pastry shells filled with a silky, smooth egg custard made from evaporated milk, sugar, and vanilla, offering a delicate wobbly center and shiny surface.
Gentle stirring instead of whisking prevents air bubbles for a smooth glossy custard surface., Straining custard is key to a silky, lump-free texture., Dock pastry shell bottoms to prevent soggy bases and allow even baking., Using metal tart pans helps shells bake evenly; avoid silicone molds for optimal crust crispness., For firmer custard, reduce hot water to 3/4 cup and increase evaporated milk by 1 tablespoon., Shortcrust pastry can be substituted for a sturdier, buttery shell though it won’t puff or flake like puff pastry., Tarts keep up to 1 day at room temperature, 3–4 days refrigerated, and freeze well wrapped individually., Reheat frozen tarts at 300°F (150°C) for about 10 minutes to warm custard gently.
