Cook ruins veal found everywhere (9)
I believe the answer is:
universal
'found everywhere' is the definition.
(I've seen this before)
'cook ruins veal' is the wordplay.
'cook' indicates an anagram.
'ruins'+'veal'='ruinsveal'
'ruinsveal' anagrammed gives 'UNIVERSAL'.
(Other definitions for universal that I've seen before include "wide-ranging and comprehensive" , "Without exception" , "affecting everyone" , "Sort of joint" , "Applicable to all cases" .)
