Frequently Asked Questions (FAQ)

How to keep Steamed Baozi?

Let the steam bun cool to room temperature. Recommended to keep baozi a airtight container in the fridge or freezer.

If kept in the fridge, it can last for about 1 week. When ready to eat, remove from fridge and steam for about 10 minutes on high heat. (note: water preboiled before steaming). Serve warm to enjoy.

If kept in the freezer, it can last for about 2-3 weeks. When ready to eat, remove from freezer and steam for about 20 minutes on high heat. (note: water preboiled before steaming). Serve warm to enjoy.

Why is my baozi not as soft and fluffy when cold or at room temperature?

Baozi or any steam cakes or breads becomes tougher when left at room temperature or cold. Baozi is always served warm or right after steaming from the steamer.

Once its cold, steam the baozi again to enjoy it the soft and fluffy baozi when its warm

Can I use all purpose flour to substitute Hong Kong flour?

Its not ideal to use all purpose flour to substitute Hong Kong flour because the the texture of the baozi is very different. All purpose flour will produce chewy buns. But Hong Kong flour will produce soft finer texture.

Also the process and the water content required is different when using all purpose flour. So its not ideal to substitute with all purpose flour

What is the best flour to substitute Hong Kong flour?

There may be other brands that sell flour specifically to make baozi. They are usually labelled as pau flour, low gluten pau flour. You may be able to find it at the Chinese Supermarket or Specialty Chinese Baking Shops. In Malaysia, I get from Bake with Yen
