Cake-making product that meant a lot to the Romans (3)
I believe the answer is:
mix
'product that meant a lot to the romans' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for mix that I've seen before include "Stir or blend" , "Amalgamate, blend" , "Blend together" , "= 1,009 (L.)" , "Combine into one" .)
