Pleasure after a sort of bath is sweet (7,7)
I believe the answer is:
turkish delight
'is sweet' is the definition.
(I've seen this before)
'pleasure after a sort of bath' is the wordplay.
'pleasure' becomes 'delight' (delight is a kind of pleasure).
'after' means one lot of letters go next to another.
'a sort of bath' becomes 'turkish' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'delight' put after 'turkish' is 'TURKISH DELIGHT'.
Can you help me to learn more?
(Other definitions for turkish delight that I've seen before include "Jelly-like confection ..." , "pleasure in Ankara" , "consequence of a future decision on EU admission?" , "Sweet" , "Confectionery" .)
