Curve about me, soft ultimately, French food (9)
I believe the answer is:
camembert
'french food' is the definition.
(I've seen this before)
'curve about me soft ultimately' is the wordplay.
'curve' becomes 'camber' (cambering is a kind of curving).
'about' is an insertion indicator.
'ultimately' indicates one should take the final letters.
The last letter of 'soft' is 't'.
'camber' going around 'me' is 'camember'.
'camember'+'t'='CAMEMBERT'
(Other definitions for camembert that I've seen before include "dairy product" , "Soft rich cheese as made in Normandy" , "French produce" , "French food" , "soft fare" .)
