Snake I caught with savoury jelly (5)
I believe the answer is:
aspic
'savoury jelly' is the definition.
(I've seen this before)
'snake i caught' is the wordplay.
'snake' becomes 'asp' (asp is a kind of snake).
'caught' becomes 'c' (cricket abbreviation).
'asp'+'i'+'c'='ASPIC'
'with' acts as a link.
(Other definitions for aspic that I've seen before include "Savoury meat or fish jelly" , "Preservative jelly" , "that's clear?" , "Lavender" , "Clear savoury jelly" .)
