Egg Tart Variants — Hong Kong vs Macau (蛋挞)

Ingredients

• For the HK shortcrust shell
• 200 g plain flour
• 120 g unsalted butter, cold, cubed
• 40 g icing sugar
• 1 egg yolk
• For the HK custard
• 2 eggs, lightly beaten
• 120 ml whole milk
• 60 ml evaporated milk
• 50 g caster sugar
• 1 tsp vanilla extract
• For the Macau puff pastry shell
• 200 g ready-laminated puff pastry, or homemade; rolled to 3 mm
• For the Macau custard
• 4 egg yolks
• 150 ml double cream
• 80 ml whole milk
• 80 g caster sugar, higher proportion than HK version
• 1 tsp vanilla extract

Method

1. 1
   HK shortcrust shell — Rub the cold butter into the flour and icing sugar until the mixture resembles coarse breadcrumbs. Add the egg yolk and bring together into a dough. Press — do not roll — directly into six shallow tart moulds, working the dough up the sides in an even layer. Refrigerate for 20 minutes. The shell is ready when it holds its shape cleanly against the mould with no cracks.
2. 2
   HK custard — Dissolve the sugar in the warm whole milk, then stir in the evaporated milk, beaten eggs, and vanilla. Pass the mixture through a fine sieve to remove all egg threads and surface foam. The liquid should fall through the sieve in a smooth, unbroken sheet.
3. 3
   HK tart — Blind-bake the chilled shells at 190 °C for 10 minutes until the pastry is set and just beginning to colour at the edges, with no raw-pale patches at the base. Pour the strained custard into each shell to within 3 mm of the rim. Return to the oven and bake at 160 °C until the custard is just set — this is where the dish lives or dies: the centre must still carry a gentle, trembling wobble when the tray is nudged; a fully still, puffed, or bubbled surface means the custard has gone past. Remove immediately.
4. 4
   Macau puff pastry shell — Cut the rolled puff pastry into rounds and press into six deeper tart moulds, allowing a slight overhang. Refrigerate for 15 minutes. The pastry should sit flush against the mould without springing back.
5. 5
   Macau custard — Whisk the egg yolks and sugar until the sugar dissolves and the mixture turns pale. Warm the cream and milk together without boiling, then pour slowly onto the yolk mixture, whisking constantly. Pass through a fine sieve. The finished liquid should be uniform in colour with no streaks of yolk.
6. 6
   Macau tart — Fill the chilled puff shells with the strained custard to within 3 mm of the rim. Bake at 220 °C until the pastry is deep golden and the custard surface carries visible caramelised patches — characteristic of the Macau version — while the centre retains a slight wobble. Do not allow the custard to puff and collapse.
7. 7
   Rest — Allow HK tarts to rest 5 minutes before unmoulding; the custard firms slightly and releases cleanly. Macau tarts must be served warm and immediately: the contrast of hot pastry and warm custard is the point of the dish. Test by pressing the pastry base lightly — it should feel crisp and set, not soft.
