Chapter 4: Char Siu, Fillings & The Tea Sauce Repertoire
Baked Sago Pudding is an absolute titan of the old-school Hong Kong dim sum parlor—a warm, deeply comforting collision of British colonial dairy and Southeast Asian sago, wrapping a sweet, earthy core of traditional lotus seed paste. It has largely vanished from the rolling carts of modern restaurants because it refuses to sit around; it demands à la minute baking. By mastering this deliberate, starch-heavy architecture at home, you reclaim the ultimate Sunday flex: delivering a bubbling, caramelized custard to the table just as the last savory bamboo steamer is cleared away.
Ingredients
- small white tapioca pearls1/2 cup
- water6 cup
- cold whole milk1/4 cup
- whole milk3/4 cup
- evaporated milk1/2 cup
- Bird's Custard Powder3 tbsp
- cornstarch1 tbsp
- granulated sugar1/3 cup
- unsalted butter2 tbsp
- large egg1 large
- large egg yolk1 large
- premium lotus seed paste1/2 cup
- whole milk1 tsp
- unsalted butter1 tbsp
Method
- 01
Hydrate the sago pearls using the traditional half-boil, half-steep method.
Bring 6 cups of water to a rapid, rolling boil. Drop the dry sago directly in and simmer vigorously for exactly 10 minutes while stirring to prevent sticking. Remove the pot entirely from the heat, cover tightly, and let steep undisturbed for 15 minutes until the opaque white cores turn completely clear.
- 02
Instantly arrest the cooking process with a cold water shock.
Drain the sago into a fine-mesh strainer and run vigorously under cold tap water. Agitate the pearls gently with your fingers to wash away excess gelatinized starch until they feel cool, distinct, and springy. Drain well and set aside.
- 03
Condition the lotus seed paste so it yields perfectly to the spoon.
In a small bowl, aggressively fold 1 teaspoon of milk into the lotus seed paste until it reaches the consistency of thick peanut butter. Divide the paste into 4 to 6 equal portions and flatten them slightly into discs.
- 04
Whisk the starches into cold milk to prevent clumping.
In a small mixing bowl, combine the custard powder, cornstarch, and 1/4 cup of the cold whole milk. Whisk aggressively until a completely smooth slurry forms.
- 05
Heat the dairy and thicken the custard base gently on the stovetop.
In a medium saucepan, gently heat the remaining 3/4 cup whole milk, evaporated milk, granulated sugar, and 2 tablespoons of butter over medium-low heat just until melted and warm. Slowly pour in the cold starch slurry in a steady stream, whisking constantly, until the mixture rapidly thickens to a mayonnaise-like consistency. Remove from heat immediately.
- 06
Temper the eggs into the thickened custard and fold in the sago.
Let the custard sit off the heat for 2 minutes. While whisking constantly, stream in the beaten egg and egg yolk so the residual heat cooks them into a glossy emulsion. Gently fold the drained sago pearls evenly into the custard.
- 07
Layer the sago custard and lotus seed paste into buttered ramekins.
Preheat your oven to 400°F (200°C). Generously butter the insides of 4 to 6 ceramic ramekins. Fill them halfway with the sago custard, place a flattened disc of lotus paste flat in the center of each, and cover with the remaining custard to about 90 percent capacity.
- 08
Bake the puddings in a hot water bath to caramelize the top while preserving a silky interior.
Place the ramekins in a deep roasting pan. Carefully pour boiling water into the pan until it reaches halfway up the sides of the ramekins. Bake for 20 to 25 minutes, until the custards puff slightly and the surfaces develop distinct, dark golden-brown, caramelized spots. Serve warm.
Notes
Understand the thermal mechanics of dim sum custards.
Unlike the zero-air-bubble, slow bake of a Hong Kong Egg Tart, this pudding relies on a high-heat bake acting like a broiler to trigger the Maillard reaction on the surface, while the water bath shields the pre-gelatinized starch suspension from curdling.
Time the bake perfectly to conclude your dim sum service.
Assemble the ramekins up to two hours in advance and leave them covered at room temperature. Pop them into the oven just as your guests are finishing their final savory bamboo steamer to ensure a hot, fresh finale.
Swap the filling or the dairy to suit your pantry or palate.
Red bean or chestnut paste are historically accurate alternatives if lotus seed paste proves too elusive. Replacing the whole milk entirely with full-fat coconut milk introduces a tropical Southeast Asian profile while retaining the necessary top-browning from the evaporated milk.
