How to Make Custard Fillings: A Comprehensive Guide

Custard fillings, with their smooth, rich texture and delicate sweetness, are a beloved staple in pastries like mooncakes, baozi, and tarts. Mastering this versatile馅料 (filling) is simpler than you think—here’s a detailed breakdown.

Basic Egg Custard Filling

Start with the classic: mix 100g egg yolks, 30g sugar, and 200g milk (or coconut milk for extra flavor). Stir until smooth, then strain through a fine-mesh sieve to remove lumps. Steam over medium heat for 20–25 minutes, stirring occasionally, until thickened. For a richer taste, add 20g melted butter and a pinch of salt.

Flavor Variations

Elevate your filling with unique twists:

- Matcha Custard: Replace 10g milk with matcha powder for a vibrant, earthy flavor.

- Mango Custard: Blend 50g fresh mango puree into the mixture before steaming.

- Salted Egg Yolk: Fold in 4–5 cooked, mashed salted egg yolks for a savory-sweet contrast.

Tips for Success

Use low heat to prevent curdling; cover the steaming bowl with parchment paper to retain moisture. For a silkier texture, blend the cooled custard until smooth. Store in the fridge for up to 3 days, or freeze for longer use.

Whether traditional or creative, custard fillings add a luxurious touch to any dessert. Experiment with flavors and enjoy the process!
