This guide is designed to help you make an informed choice. We'll walk you through what to look for when you buy custard buns online and share some of our top recommendations, whether you're a fan of the classic sweet nai wong bao or the indulgent, savoury liu sha bao.

How to Choose Your Perfect Steamed Custard Buns

Before adding a pack to your basket, consider a few key points. Understanding these small details can make all the difference between a good and a great at-home dim sum experience.

1. Sweet or Savoury: Know Your Custard

The term "custard bun" can refer to two popular, yet distinct, types of filling. Knowing the difference is the first step to finding your favourite.

• Nai Wong Bao (奶黃包): This is the classic sweet custard bun. It features a firm, sweet and creamy filling with a rich, milky flavour. It’s a comforting and familiar taste, often enjoyed for breakfast or as a simple dessert.
• Liu Sha Bao (流沙包): Known as the "flowing sand bun," this version contains a molten centre made from salted duck egg yolk. The filling is a delightful combination of sweet and savoury, and it's designed to ooze out when you break the bun open. It offers a more complex and indulgent flavour profile.

2. Check the Ingredients and Allergens

For any food product, a quick look at the label is always a good idea. When choosing Chinese steamed buns, pay attention to common allergens such as WHEAT, EGG, MILK and SOYBEANS. The ingredients list will also confirm the type of filling used, whether it's a classic custard powder base or one featuring salted duck egg yolk, helping you match the product to your taste preference.

3. Preparation and Storage

The convenience of frozen custard buns lies in their simple preparation. Most are designed to be steamed directly from frozen, typically taking around 8-10 minutes. Always check the packaging for specific instructions. For storage, ensure you can maintain a temperature of -18°C or below in your freezer to keep them in prime condition until you're ready to enjoy them.

Frequently Asked Questions

What is the difference between nai wong bao and liu sha bao?

The main difference is the filling. Nai wong bao contains a solid, sweet, milk-based custard, similar to a firm pastry cream. Liu sha bao, or "flowing sand bun," has a molten centre made with salted duck egg yolks, giving it a unique sweet-and-savoury flavour that oozes out when warm.

How do I cook frozen custard buns?

The most common and effective method is steaming. Place the frozen buns in a steamer over boiling water and steam for approximately 8-10 minutes, or until they are heated through, soft and fluffy. Avoid microwaving, as it can make the buns tough and dry. Always refer to the specific cooking instructions on the product packaging.

Can I buy authentic frozen custard buns online in the UK?

Yes, absolutely. Many online retailers now specialise in delivering high-quality frozen dim sum and other East Asian foods directly to homes across the UK.
