FAQs

What makes Chinese hot mustard spicy?

The heat comes from mustard powder reacting with water to release natural enzymes that create the signature sharp bite.

Can I use regular yellow mustard instead?

No, prepared yellow mustard is milder and not a good substitute. Use dry mustard powder for authentic flavor.

Why does it taste so strong?

The mustard is meant to be pungent and is usually used in small amounts. You can mellow it by adding vinegar or sugar.

Is it gluten-free?

Yes, as long as your mustard powder is pure and not cross-contaminated.

Can I store it at room temperature?

It’s best stored in the fridge to maintain freshness and food safety.

Why is it watery or separating?

Give it a good stir before serving—separation is normal with simple homemade condiments.

Can I use cold water?

Hot water activates the mustard powder more effectively for stronger flavor.

Is Chinese mustard healthy?

Yes, it’s low in calories and has no fat or sugar unless added for flavor balance.

How do I tone down the heat?

Let it sit longer before serving or add vinegar, sugar, or a creamy base like mayo.
