Mastering Mentsuyu: The Essential Japanese Multi-Purpose Sauce

Featuring Handcrafted Mentsuyu, Zaru Soba, Takikomi Gohan & Pan-Fried Kakiage)

If you love authentic Japanese flavors and want practical techniques for your home cooking, this hands-on workshop is for you.

You will learn to make mentsuyu—the foundational, multi-purpose seasoned sauce at the heart of everyday Japanese cooking. Made from a simple, balanced mix of soy sauce, mirin, and rich umami broth, mentsuyu works as a noodle dipping sauce, rice seasoning, salad dressing, and quick marinade.

Rather than aiming to build a single formal dinner, this class is designed to showcase the incredible range of what mentsuyu can do in your everyday kitchen. We will simmer a batch from scratch, explore how subtle adjustments change the flavor profile, and prepare a varied tasting menu featuring noodles, seasoned rice, fried seasonal vegetables, and fresh greens.
