Endless condiment put on food, jump! (7)
I believe the answer is:
salchow
'jump' is the definition.
(I've seen this before)
'endless condiment put on food' is the wordplay.
'endless' means to remove the last letter.
'condiment' becomes 'salt' (I've seen this before).
'put on' means one lot of letters go next to another.
'food' becomes 'chow' (chow is a kind of food**).
'salt' with its last letter removed is 'sal'.
'sal'+'chow'='SALCHOW'
(Other definitions for salchow that I've seen before include "twisting leap" , "Jump with spins on ice" .)
