redcurrant

I'm a little stuck... Click here to teach me more about this clue!

'fruit' is the definition.
(redcurrant is a kind of fruit)

'declared in vogue reportedly' is the wordplay.
'declared' becomes 'red' (I can't explain this - if you can you should believe this answer much more).
'in vogue' becomes 'current' (I've seen this before).
'reportedly' shows a homophone (sound like).
'current' sounds like 'currant'.
'red'+'currant'='REDCURRANT'

Can you help me to learn more?

(Other definitions for redcurrant that I've seen before include "Gooseberry's relative" , "Fruit" .)
