A tongue getting ready for something tasty (6,8)
I believe the answer is:
french dressing
'a tongue' is the definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps there's an association between them I don't understand?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for french dressing that I've seen before include "Something going on salad" , "haute couture?" , "Maybe relish" , "sauce for salad" , "vinaigrette!'" .)
