Here's everything worth knowing about chinese hot mustard and how to pick it, what it is, how to store it, and what to use instead, plus 9 recipes to cook tonight.
Chinese hot mustard is the eye-watering yellow paste served alongside egg rolls and dumplings at American Chinese restaurants. It is little more than dry mustard powder stirred into water, with nothing added to soften it.
That is why it hits so much harder than the squeeze-bottle yellow mustard most people know.
The seeds used are brown and Oriental mustard, the same hot varieties behind English mustard. Mixing the powder with cool water triggers an enzyme reaction that produces the sharp, sinus-clearing pungency. Hot water or vinegar would blunt it, so plain cold water is the trick.
That heat is fleeting. It blooms on the nose, then peaks and vanishes within a minute, leaving none of the lingering burn you get from chillies.
Mix it fresh. Stir one part mustard powder with about one part cool water into a smooth paste, then let it rest ten to fifteen minutes so the pungency fully develops before serving.
It is first a dipping condiment. Set out a small dish for fried wontons or spring rolls, where a tiny dab on each bite is the point.
Beyond the dip, it loosens easily into sauces and dressings. Whisk a little into soy and sesame for a salad, as in the Asian Colorful Broccoli Salad.
It also works into a marinade for roasts and pork, the way Pork Tenderloin Perfection and Eye of Round Roast use it for a sharp savoury edge.
Keep the dose tiny. A quarter teaspoon goes a long way, and the freshly mixed paste is at its fiercest within the first hour.
This mustard was built for rich, fatty, fried food. Crab rangoon, roast pork, and crispy noodles all give the heat something to cut, and a drop of soy or a pinch of sugar rounds it out without dulling it.
It also wakes up a brothy bowl like Four Treasure Soup, adding a clean sharp jolt when stirred in at the table.
The biggest mistake is mixing it with hot liquid. Heat destroys the enzyme that creates the pungency, so a paste made with warm water comes out flat and bitter rather than hot. Always use cool water.
The second mistake is making it too far ahead. The heat starts fading after an hour and is much weaker by the next day, so mix it close to serving rather than storing a big batch.
English mustard is the closest match by a wide margin, since it is the same kind of hot mustard powder and water. Use it one for one.
Wasabi or fresh horseradish gives a similar nose-hitting heat with a different flavour, and works when you want that clearing sharpness in a pinch. Start with half as much and adjust.
Hot mustard powder mixed yourself is really the authentic version, so if you have Colman's or any dry mustard, you already have what you need. Plain prepared yellow mustard is not a substitute; it is far milder and more vinegary, and no amount will give you the same kick.
You can buy Chinese hot mustard as a ready-made paste in jars or small packets, but the powder is the better choice. It costs less and keeps for years, and lets you mix only as much as you need so it is always at full strength.
Dry mustard powder stays good two to three years in a sealed container kept cool and dry. Once mixed, the paste should be covered and refrigerated, but plan to use it within a day or two while it still has bite.
Those little takeout packets keep almost indefinitely unopened, which makes them handy to stash, though a freshly mixed batch will always be hotter.
