What Is Hot Mustard (Gyeoja)?
Hot mustard, otherwise known as ‘gyeoja’ (겨자) in the Korean language, is an ingredient made by grinding mustard seeds into a bright yellow-orange powder.
In Korea, you can find this ingredient at the grocery store in two forms:
- Yeon Gyeoja (연겨자): Pre-made hot mustard paste in a tube, or
- Gyeojagaru (겨자가루): Powdered mustard that you mix with warm water to make the paste at home
Hot Mustard in Korean Cuisine:
As stated above, in South Korea, people refer to hot mustard as ‘gyeoja’ (겨자). Culturally, they use this ingredient sparingly as a condiment to add heat to dishes. Below, I list a few well-known Korean foods that often include this ingredient:
- Mul Naengmyeon (물냉면): Korean cold noodle soup
- Makguksu (막국수): Buckwheat noodle salad
- Haepari Naengchae (해파리냉채): Cold jellyfish salad
Hot Mustard (Gyeoja) Frequently Asked Questions:
Now that we learned about gyeoja in Korean cuisine, I want to answer some questions you may have about this ingredient! If I do not answer your question, feel free to leave a comment in the section below or email me at [email protected].
What Does Gyeoja Taste Like?
Korean hot mustard has a similar flavor profile to Japanese wasabi or horseradish. This potent ingredient has a sharp, zesty, and spicy flavor that will clear your sinuses and shock your system.
Where Can I Buy This Ingredient?
Sometimes, you can find a similar ingredient in your local well-stocked grocery store on the International and/or Asian aisle. While they may not carry Korean hot mustard, they may carry Oriental mustard from China or Japan.
You can also find this ingredient at your local Asian grocery store or online! As I stated above, you can buy this ingredient in two forms. You can buy it as a pre-made paste or, you can buy it in powder form!
Note: If you buy the paste, look at the ingredients. Often, it contains more than just water and mustard powder. For those with allergies, it may be better to buy the powder ingredient even though it is not as convenient.
How Do I Properly Store Korean Hot Mustard?
If you buy mustard paste, I recommend storing it in the refrigerator. Like anything processed, it will last longer and more safely in a cool location.
If you buy mustard powder, recommend storing it with the rest of your spices. Typically, you should store all your spices in a cool, dark place like the pantry or a cabinet.
What Is a Korean Hot Mustard Substitute?
As I stated above, if you cannot find Korean hot mustard, you can substitute it with Chinese or Japanese hot mustard. These products are very similar, if not identical.
