Foods should not be too hot or too cold. And it must mix with a little water (cooking) otherwise the mixer is blocked and you have to shake the pot ... After a few tries, it's great practice! Much more than the big blender! The four pots allow to chain several different product mixes with minimal dishes. Not tried conservation in freezer, so no opinion on that. One star less for the price, like all Kenwood accessories, but I do not regret my purchase.
