Fry bananas on both sides in vegetable oil until Golden brown.
Prepare a glass of very cold water.
In the remaining oil, dissolve the sugar to a caramel state (so that the color changes to a pleasant caramel) pour sesame into it.
Put in caramel fried bananas and mix well. Sticks (or fork/spoon), which you will remove bananas from the pan, keep in cold water to caramel them not stuck. Take each piece and dip in water, and then put on a plate to solidify.
Place the bananas on a plate and allow to cool.
When serving, decorate bananas with a sprig of mint.
