Some people microwave their cold onigiri. Heathen! cries one camp. Genius! shouts the other. Microwaving turns the nori into a rubbery ghost—but the rice becomes fluffy again. It’s a gamble. You might get a texture that feels like wet cardboard hugging warm clouds. I’m not saying it’s bad. I’m saying it’s an experience.
Here’s a fun, weird fact: in Japanese convenience stores, onigiri is never stored in a refrigerator. It sits at room temperature. Why? Because cold ruins the rice’s mouthfeel. That’s right—proper onigiri is meant to be eaten at ambient temperature. Neither hot nor cold. It’s the Goldilocks zone of rice balls. So technically, the whole debate is a myth. Shh—don’t tell anyone.
