In Puglia, peeled sweet fruit (4)

I believe the answer is:

ugli

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

'sweet fruit' is the definition.
'ugli' can be an answer for 'fruit' (ugli is a kind of fruit). I am unsure of the 'sweet' bit.

'in puglia peeled' is the wordplay.
'in' indicates the answer is hidden within the clue.
'UGLI' is hidden in the letters of 'puglia peeled'.

Can you help me to learn more?

(Other definitions for ugli that I've seen before include "Plain-sounding fruit" , "Unattractive-sounding fruit?" , "mixed fruit" , "Black/violet element" , "Grapefruit/tangerine hybrid" .)

I've seen this clue in The Everyman puzzle in The Observer.
