What is it?
Crungji is a Korean rice snack inspired by nurungji, the crisp scorched rice that forms at the bottom of the pot. The rice is pressed into thin, crunchy crackers and lightly salted or sweetened.
Convenience stores in Seoul, where summers run around 27°C and humid, stock it as a lighter alternative to potato chips, and it became a popular souvenir snack for visitors.
The texture is very crunchy with a toasty, roasted-rice aroma and just a hint of salt or sweetness.

How we tested
Reference by Y.W. Fung at 82kg with an Apple Watch Ultra. The reference route is a 5.3-mile loop at 3.1 mph walking and 6 mph running; food burn minutes are calculated from calories at those rates, not individually walked off for every food. The reference test date is 2026-05-20. Check the food's listed source and serving.
In Seoul and Tokyo, where summers are usually around 27°C and humid, a longer walk in the heat can feel harder than the reference loop shown here.
