Meat cooked thus? Congratulations! (4,4)
I believe the answer is:
well done
'congratulations' is the definition.
(I've seen this before)
'meat cooked thus?' is the wordplay.
I cannot really see how this works, but
'cooked' could be 'done' (similar in meaning) and 'done' is found in the answer.
The remaining letters 'well' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for well done that I've seen before include "Words of praise" , "By no means rare" , "Commendation for achievement" , "thoroughly prepared" , "how a steak may have been cooked" .)
