Vegetable highly thought of in France (5)

I believe the answer is:

savoy

I'm a little stuck... Click here to teach me more about this clue!

'in france' is the definition.
(I know that Savoy is part of France)

I can't explain the rest of the clue.

(Other definitions for savoy that I've seen before include "Type of cabbage - London theatre" , "A cabbage; some Operas" , "Dense cabbage" , "Cabbage; hotel" , "area of France" .)

I've seen this clue in The Globe and Mail.
