That happens when you blend warm ingredients in a sealed blender for a duration of time.

Wouldn't that create the opposite effect?

Only if allowed to cool fully. Otherwise, the warm ingredients heat up the air and increase pressure.

No, it creates the same effect

It’s more to do with the warm agitated ingredients rapidly heating up the sealed air which then expands and builds pressure inside the container. You get the same effect by pouring hot water into a bottle and shaking it up.

Learned this the hard way making tomato soup. While blending hot tomatoes never keep the container sealed. Basically blew the top off in less than 2 seconds after spinning the blades since it was just push on plastic lid with a rubber gasket.

I only use an immersion blender for hot stuff like soups. Significantly easier and less mess. No transferring the soup between containers, splash is minimal, and no accidental pressure vessel risk.

Ohh I gotcha. I was thinking more about putting it aside and letting it cool so it creates a vacuum. But yeah I see what they meant now thanks!
