From start to finish I run turning over pancake (8)
I believe the answer is:
tortilla
'pancake' is the definition.
(I know that tortilla is a type of tortilla\nI know that tortilla is a type of battercake\nTherefore, tortilla is a type of battercake)
'from start to finish i run turning' is the wordplay.
'from start to finish' becomes 'all'.
'run' becomes 'trot' (trot is a kind of run).
'turning' says the letters should be written backwards.
'all'+'i'+'trot'='allitrot'
'allitrot' written backwards gives 'TORTILLA'.
'over' acts as a link.
(Other definitions for tortilla that I've seen before include "Mexican corn-meal pancake" , "Thin unleavened pancake" , "hot meal?" , "Littoral (anag.)" , "Mexican snack" .)
