Vitamin added to a dairy product made well (5)
I believe the answer is:
cured
'made well' is the definition.
(I've seen this before)
'vitamin added to a dairy product' is the wordplay.
I cannot quite understand how this works, but
'vitamin' could be 'e' (E is an example) and 'e' is found within the answer.
'dairy product' could be 'curd' (curd is a kind of dairy product) and 'curd' is found within the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for cured that I've seen before include "Made better or preserved" , "Healed - smoked" , "Mended" , "Healed - preserved" , "Healed or salted" .)
