Soak up solidified lemony dessert (6)
I believe the answer is:
posset
'lemony dessert' is the definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'soak up solidified' is the wordplay.
'soak' becomes 'sop' ('sop' can be a synonym of 'soak').
'up' says the letters should be written backwards (in down clue: letters go upwards).
'solidified' becomes 'set' (I've seen this before).
'sop' written backwards gives 'pos'.
'pos'+'set'='POSSET'
Can you help me to learn more?
(Other definitions for posset that I've seen before include "So step on curdled milk once used as a cold remedy" , "As relief for cold" , "Sweet spiced milk curdled with alcohol" , "Curdled milk drink" .)
