Some recipes from the east of impressive proportions (4)
I believe the answer is:
epic
'of impressive proportions' is the definition.
'some recipes from the east' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'from the east' is a reversal indicator.
'cipe' is hidden in the letters of 'recipes'.
'cipe' in reverse letter order is 'EPIC'.
(Other definitions for epic that I've seen before include "Heroic poem, film" , "Blown up" , "Vast in scale" , "Long poem - awesome!" , "Large in scale" .)
