English artist who can decorate cakes (5)
I believe the answer is:
piper
'english artist' is the definition.
(I know that Piper was a english artist)
'decorate cakes' is the wordplay.
'decorate' becomes 'pipe' (piping is a kind of decorating).
'cakes' becomes 'r' (I can't explain this - if you can you should give a lot more credence to this answer).
'pipe'+'r'='PIPER'
'who can' acts as a link.
Can you help me to learn more?
(Other definitions for piper that I've seen before include "English painter and stained glass designer, d. 1992" , "Scots musician" , "who puffs out his cheeks?" , "He who pays him, calls the tune" , "oil and gas field" .)
