A dish like hot dog? (5)
I believe the answer is:
curry
'a dish' is the definition.
(I know that curry is a type of dish)
'like hot dog?' is the wordplay.
I cannot really understand how this works, but
'like' could be 'y' (similar in meaning) and 'y' is present in the answer.
'dog?' could be 'cur' (both can mean a despicable person) and 'cur' is present in the answer.
A single letter 'r' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for curry that I've seen before include "Scratch" , "This powder is a mixture of spices" , "Indian-style dish" , "Vindaloo, for example" , "food" .)
