Pale ale endlessly used in stew (6)
I believe the answer is:
paella
'stew' is the definition.
(I've seen this before)
'pale ale endlessly used' is the wordplay.
'endlessly' means to remove the last letter.
'used' indicates an anagram.
'pale'+'ale'='paleale'
'paleale' with its final letter taken off is 'paleal'.
'paleal' anagrammed gives 'PAELLA'.
'in' is the link.
(Other definitions for paella that I've seen before include "something to eat" , "Spanish dish of rice, chicken, seafood etc cooked in a pan" , "Spanish dish based on saffron rice" , "Spanish course" , "Make stew" .)
