Blistering (3-3)
I believe the answer is:
red-hot
'blistering' is the definition.
(I know that blistering can be written as red-hot)
This is all the clue.
(Other definitions for red-hot that I've seen before include "Glowing with heat" , "Very good" , "likely to win" , "Most recent - glowing" , "(Of information) very recently received" .)
