Touching new peach, extremely gentle heat (9)
I believe the answer is:
repechage
'heat' is the definition.
(I've seen this before)
'touching new peach extremely gentle' is the wordplay.
'touching' becomes 're' (I've seen this in other clues).
'new' indicates anagramming the letters.
'extremely' says to hollow out the word (remove centre letters).
'gentle' with its centre taken out is 'ge'.
'peach' with letters rearranged gives 'pecha'.
're'+'pecha'+'ge'='REPECHAGE'
(Other definitions for repechage that I've seen before include "Additional qualifying round in certain sports, eg fencing, rowing" , "supplementary heat" .)
