I believe the answer is:

fresh

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

'is extra' is the definition.
(as in 'fresh blood')

I don't understand how the remainder of the clue works.

(Other definitions for fresh that I've seen before include "Saucy" , "New-fangled" , "Invigorating" , "Straight" , "Cheeky (sl.)" .)

I've seen this clue in The Telegraph.
