American loaves maybe react to the addition of yeast, it's said (4)
I believe the answer is:
ryes
'american loaves' is the definition.
The answer and definition can be both things that one consumes for nourishment as well as being plural nouns.
Maybe you can see an association between them that I don't see?
'maybe react to the addition of yeast it's said' is the wordplay.
I cannot quite understand how this works, but
'it's' could be 'es' ('e' can mean 'electronic' which is similar to 'IT') and 'es' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for ryes that I've seen is " cereals".)
