Rolled pastry, extremely short, ruled revolting (7)
I believe the answer is:
strudel
'rolled pastry' is the definition.
'strudel' can be an answer for 'pastry' (strudel is a kind of pastry). I am unsure of the 'rolled' bit.
'extremely short ruled revolting' is the wordplay.
'extremely' suggests removing the centre.
'revolting' is an anagram indicator.
'short' with its centre removed is 'st'.
'ruled' is an anagram of 'rudel'.
'st'+'rudel'='STRUDEL'
Can you help me to learn more?
(Other definitions for strudel that I've seen before include "A German baked pastry" , "Germany pastry" , "See 6" , "German dessert" , "Dessert of thin pastry filled with fruit" .)
