The definition is at the beginning of the clue.
How the clue works
The definition is Wrap, referring to a TORTILLA. The wordplay builds the answer in reverse: "everything" gives ALL, then I (from the clue), and "jog" gives TROT. Put together that's ALL + I + TROT, and "back" tells you to reverse the whole lot, giving TORTI + LLA = TORTILLA.
