Cut the over sized banana leaf to the size needed, leaving the thick membrane at the one side of the leave intact.

Pass over the open flame quickly, a couple of times, until the leaf turns bright green and glossy.

Place the banana leave on a chopping board and cut it to the size required, ensuring that the thick membrane on the one side and the loose, wavy edges of the leaf on the other, are neatly cut off.

The banana leaf is now ready to be used.
