Hot place in Provence (4)
I believe the answer is:
oven
'hot place' is the definition.
(I've seen this in another clue)
'in provence' is the wordplay.
'in' indicates the answer is hidden within the clue.
'OVEN' is hidden in the letters of 'provence'.
(Other definitions for oven that I've seen before include "It may get very hot" , "Kiln, perhaps" , "Hot spot" , "Meat is roasted in it" , "Metal box in which to roast" .)
