EXPLORE and PRACTICE Japanese cooking in your own kitchenAbout Kitchen Culture Cooking Club
Welcome to the Kitchen Culture Cooking Club, a community space providing encouragement to those who want to EXPLORE and PRACTICE Japan’s washoku wisdom in their own kitchens.
To facilitate this, themed projects will be posted to this page periodically. Project Assignments and links to relevant reference material stored on this site will be posted to this page. Anyone, anywhere in the world, with a sincere interest in Japanese food culture is welcome to browse the contents of this page and then replicate the themed project in their own kitchen.
For those who wish to display-and-discuss their projects with like-minded people, I invite you to join the KITCHEN CULTURE Cooking Club Facebook Group (formerly the TSUDOI Project), an interactive community space.
PROJECT Tonburi

PROJECT TONBURI
Tonburi, the seeds of the broom plant, are tiny and black-green in color. Because they mimic the appearance and mouthfeel of sturgeon caviar tonburi is often referred to as hataké no kyabia (“caviar of the field”). Akita prefecture in the Tohoku produces most of Japan’s commercial crop.
Tonburi is sold in vacuum-sealed pouches and in small glass jars. Store in a cool, dark, dry spot until opening. After opening, refrigerate and use within 2 weeks.

Using TONBURI
Inhabitants of the Tohoku region enjoy tonburi in three ways:
- aé mono: tossed in with other foodstuffs
- mazé mono: mixed with other foodstuffs
- chirasu mono: scattered over other foodstuffs
If you are able to source tonburi, try using as a topping for tōfu, rice or noodles (Japanese sōmen, soba or any pasta)… or toss with rice and shape into onigiri… or, serve with vegetables.
