'essential ingredients of bread salami and omelette' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'craft beer' is the wordplay.
'craft' becomes 'real' (I can't justify this - if you can you should believe this answer much more).
'beer' becomes 'ale' (type of beer).
'real'+'ale'='REALALE'

'and' acts as a link.
