🍲 Instructions — 5 quick steps
1
Soften the noodles
Reconstitute harusame according to the packet (usually a 3-minute soak in boiling water). Drain and rinse under cold water until chilled; set aside.
2
Build a speedy stock
In the food jar, whisk dashi powder, soy, vinegar, sesame oil, sugar and the ½ cup of freshly boiled water until everything dissolves.
3
Instant chill
Tip in the ice cubes. Swirl once—this drops the temperature fast so your extras stay crisp.
4
Load the goodies
Add the cooled noodles plus your chosen toppings.
5
Top up & seal
Pour in cold water until the level sits 1 cm beneath the ridge, secure the lid and give the jar a gentle shake. Your noodles are ready right away and will stay refreshingly cool for up to six hours—perfect for Zojirushi lunch jar meals on scorching days.
💡 Tip or Advice

- Kids’ lunch hack: Swap kimchi for sweetcorn and julienned carrots; the mild broth still earns points among hot food ideas for kids school lunch fans—just served cold!
- Make it vegan: Replace dashi with kombu powder and up the sesame oil for extra body.
