'meals that are really just booze' is the definition.

'ps51 uncle's blown consuming hot' is the wordplay.
I cannot quite understand how this works, but
'hot' could be 'h' (abbreviation eg on taps) and 'h' is found within the answer.
an anagram of 'uncle' is 'lunce' which is located in the left over letters.
The remaining letters 'liquids' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
