Very hot chilli pepper (8)
I believe the answer is:
jalapeno
'very hot chilli pepper' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for jalapeno that I've seen before include "Hot type of capsicum pepper" , "Green chilli pepper used in Mexican cooking" , "Variety of chilli" , "Hot green chilli" , "something really hot" .)
