This filling simmers coconut milk, sugar, and egg yolks into a rich custard, then sets it with agar agar for a sliceable, glossy texture. It works as a layer in cakes and pastries or chilled on its own as a light coconut dessert, common in Southeast Asian layered sweets.
Ingredients
- 2 cups full-fat coconut milk
- 1/2 cup granulated sugar
- 2 teaspoons agar agar powder
- 3 egg yolks, lightly beaten
- 2 tablespoons cornstarch
- 1/4 cup water
- 1/4 teaspoon salt
- 1 teaspoon vanilla extract
Method
-
In a small bowl, whisk the cornstarch into the water until smooth and set aside.
-
In a 6-quart saucepan, whisk together the coconut milk, sugar, agar agar powder, and salt.
-
Bring the coconut milk mixture to a boil over medium heat, whisking frequently, then reduce heat and simmer for 3 minutes to fully dissolve the agar.
-
Ladle about 1/2 cup of the hot coconut mixture into the beaten egg yolks, whisking constantly to temper them.
-
Whisk the tempered yolks back into the saucepan along with the cornstarch slurry.
-
Cook over medium-low heat, stirring constantly, until the custard thickens and coats the back of a spoon, about 5 minutes.
-
Remove from heat and stir in the vanilla extract.
-
Pour the custard into a clean container or directly into a cake layer mold, smoothing the top with a spatula.
-
Let cool at room temperature for 15 minutes, then refrigerate until fully set and firm, at least 2 hours.
