Mushy peas and rice stored in iron apparatus for emergency use (4,6)
I believe the answer is:
fire escape
'apparatus for emergency use' is the definition.
I can't tell whether this definition defines the answer.
'mushy peas and rice stored in iron' is the wordplay.
'mushy' indicates an anagram (letters mushed up).
'and' is a charade indicator (letters next to each other).
'stored in' means one lot of letters goes inside another.
'iron' becomes 'Fe' (chemical symbol for iron).
'peas' after 'rice' is 'ricepeas'.
'ricepeas' with letters rearranged gives 'ireescap'.
'ireescap' placed into 'fe' is 'FIRE-ESCAPE'.
Can you help me to learn more?
(Other definitions for fire escape that I've seen before include "rescue apparatus" , "it could be a life-saver" , "Emergency exit" , "steps outside" , "get-out" .)
