Surprising dangers eating cold meat (5,3)
I believe the answer is:
scrag end
'meat' is the definition.
(scrag end is a kind of meat)
'surprising dangers eating cold' is the wordplay.
'surprising' is an anagram indicator.
'eating' indicates putting letters inside.
'cold' becomes 'c' (eg on taps).
'dangers' anagrammed gives 'sragend'.
'sragend' going around 'c' is 'SCRAG-END'.
(Other definitions for scrag end that I've seen before include "Bony part of neck of veal or mutton" , "Meat" , "Cut inferior" , "Inferior mutton" , "Lean piece of veal or mutton" .)
