Karashi is Japanese hot mustard, and this powdered version from S&B, Japan’s foremost spice house, delivers its authentic, unmistakable flavour. This hot mustard powder is known for a fiery, pungent heat that is noticeably sharper and cleaner than Western mustards, a bright, nose tingling kick rather than a rounded, tangy one, because it is made simply from ground mustard seed without the vinegar and sugar of European styles.

As a dry powder it is prepared fresh by mixing with a little lukewarm water and leaving it to rest for a few minutes, which activates and develops its full, sharp heat. This lets a kitchen make up exactly what it needs and control the strength, while the sealed powder keeps its potency far longer than a ready made paste.

Its heat is used as a precise accent rather than a spread. A small dab is the traditional partner to oden hot pot, tonkatsu, shumai dumplings and natto, and it lifts dressings, dipping sauces and marinades with a clean, penetrating warmth. A little goes a long way, making the 400g tin an economical, long lasting staple for a Japanese kitchen.
