Tupperware's thermos porridge is not bad. Why?

First of all, you need to confirm whether your Tupperware thermos is genuine (Tupperware doesn't have any online stores, only physical stores). It's not good to say this, but we still need to confirm it.

Then, did you spend a long time? The insulation effect of the thermos cup is not so good, or the silicone ring on the small lid inside has fallen off.

Finally, its porridge is actually cooked, and it will definitely not be the kind of porridge that blooms slowly with a small fire. But it tastes good, mainly because it is convenient. You can stew it in boiling water at night and drink it in the morning.
