Quiet president allowed to make crumpet (7)
I believe the answer is:
pikelet
'crumpet' is the definition.
(I've seen this before)
'quiet president allowed' is the wordplay.
'quiet' becomes 'p' (music symbol for 'piano').
'president' becomes 'ike' (I've seen this before**).
'allowed' becomes 'let' (I've seen this before).
'p'+'ike'+'let'='PIKELET'
'to make' is the link.
(Other definitions for pikelet that I've seen before include "afternoon treat, perhaps" , "15 [TEACAKE]" , "Thin kind of crumpet" , "local crumpet" , "Type of crumpet" .)
