Doris has her ingredients for sauce (11)
I believe the answer is:
horseradish
'sauce' is the definition.
(horseradish sauce is a kind of sauce)
'doris has her ingredients' is the wordplay.
'ingredients' indicates an anagram.
'doris'+'has'+'her'='dorishasher'
'dorishasher' is an anagram of 'HORSERADISH'.
'for' acts as a link.
(Other definitions for horseradish that I've seen before include "Saucy root vegetable?" , "Plant with hot root" , "Root used in sauce" , "type of sauce" , "Plant with root used for pungent condiment" .)
