I'm a little stuck... Click here to teach me more about this clue!

'cold things' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.

'contains' says the answer is hidden in the clue.
'ICE' is hidden within 'juicer'.

Can you help me to learn more?
