Hear yours truly yodel in sweet coat? (5)
I believe the answer is:
icing
'sweet coat?' is the definition.
(I've seen this in another clue)
'hear yours truly yodel in' is the wordplay.
I cannot quite understand how this works, but
'in' is found in the answer.
'yours truly' could be 'i' (the person that set this crossword) and 'i' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for icing that I've seen before include "Sweet thing" , "Maybe Madeira's topping" , "Possibly the nicest part of the cake" , "Attractive addition or bonus, as on cake" , "Cake-topper" .)
