Japanese Mustard Powder - Organic

Yamasei Organic Japanese Mustard Powder is crafted in Kagawa Prefecture from stone-ground organic Barukan mustard seeds, known for their fiery heat and rich mustard flavor. This karashi delivers a sharp, lingering spice while preserving the bold, pure taste of mustard. Yamasei takes special care in removing the oil and grinding the seeds to maintain their intense flavor. Perfect for adding a zesty kick to Pork Belly Kakuni, Japanese Potato Salad, and Karashi Cucumbers.

To prepare, mix four parts mustard powder with five parts lukewarm water and let it rest for 5–15 minutes to develop its full heat and complexity—never with boiling or cold water. Use immediately after resting for the freshest, most aromatic experience.
