It makes a delightful starter, blended and frozen (5)
I believe the answer is:
gelid
'frozen' is the definition.
(I've seen this in another clue)
'it makes a delightful starter blended' is the wordplay.
I cannot quite see how this works, but
'it' could be 'e' ('e' can mean 'electronic' which is similar to 'IT') and 'e' is located in the answer.
'starter' could be 'l' (as in a learner driver with L-plates on their car) and 'l' is located in the answer.
The remaining letters 'gid' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'and' acts as a link.
Can you help me to learn more?
(Other definitions for gelid that I've seen before include "Glacial" , "Icy cold - glide (anag)" , "Extremely cold, frozen" .)
