Source of beef from dodgy bangers and legume used regularly? (8,5)
I believe the answer is:
aberdeen angus
'source of beef' is the definition.
(Aberdeen Angus is a type of cow)
'dodgy bangers and legume used regularly?' is the wordplay.
'dodgy' indicates an anagram (a dodgy or wrong order of the letters).
'used regularly?' indicates alternate letters.
The alternate letters of 'legume' are 'eue'.
'bangers'+'and'+'eue'='bangersandeue'
'bangersandeue' anagrammed gives 'ABERDEEN ANGUS'.
'from' is the link.
(Other definitions for aberdeen angus that I've seen before include "Farm animal" , "Scottish black bovine" , "Type of cattle" , "Lower" , "Joint supplier" .)
