Bread and jus from San Juan (4)
I believe the answer is:
naan
'bread' is the definition.
(I've seen this before)
'and jus from san juan' is the wordplay.
'and' becomes 'n' (common abbreviation for 'and').
'jus from san juan' becomes 'aan' (I can't explain this - if you can you should believe this answer much more).
'n'+'aan'='NAAN'
Can you help me to learn more?
(Other definitions for naan that I've seen before include "foreign food" , "Indian leavened bread" , "Indian flat bread" , "Indian bread shaped like a teardrop" , "Slightly leavened bread" .)
