In a plate, spread out the sugar.
Peel the bananas and slice lengthwise into halves
Coat well on all sides with sugar. If the sugar doesn't suffice, add some more, so all the bananas are well coated.
Add butter to the pan, place on heat and swirl to melt and coat the pan.
Gently place the sugar coated bananas in a single layer on the hot pan. Allow to caramelise on medium heat.
Do not shake the pan for 4-5 minutes. The side of the bananas touching the pan will turn glistening golden brown. This may take shorter or longer depending on the variety of bananas, do not allow them to fall apart or turn mushy.
Using tongs, flip over to the other side gently. Allow this side to caramelise as well, another 4-5 minutes. If the bananas are still firm, you can caramelise them for some more time so they turn a deep golden.
Remove on to a dish and keep covered with cling wrap until use.
