Uses the oven (6)
I believe the answer is:
roasts
'uses the oven' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for roasts that I've seen before include "Has a go at" , "gets very hot" , "Cooks in dry heat" , "traditional Sunday food" , "Cooks meat in oven" .)
