gammon

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

'cured ham' is the definition.
(I've seen this before)

I cannot understand how the remainder of the clue works.

(Other definitions for gammon that I've seen before include "humbug!" , "Bottom piece of a side of bacon" , "Cured or smoked ham" , "Cured meat of hindquarters of a pig" , "Smoked pig meat" .)

I've seen this clue in The Telegraph.
