Waste time making a fried concoction (7)
I believe the answer is:
fritter
This might be a double definition.
'waste time' is the first definition.
'fritter' can be an answer for 'waste' (frittering is a kind of wasting). I am not sure about the 'time' bit.
'a fried concoction' is the second definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
I also know that 'fried' relates to this answer.
'making' acts as a link.
Can you help me to learn more?
(Other definitions for fritter that I've seen before include "Squander - fried dish" , "Spend money frivolously" , "Something battered and fried" , "bit of batter" , "Item cooked in batter" .)
