Deep fried banana is a must that you must eat when you visit Thailand. Okay it might not not be the healthiest dish but it does taste great! There has been little variation in the times that I have had it - although it does taste good with ice-cream or a heavy serving of creamed sugar.
All of the times that I have seen it made the slices of banana are first dipped into a batter, sometimes containing desiccated coconut.
Then the bananas are put into a bowl of bubbling oils.
The cooking bananas are continually turned and moved about - to ensure they do not stick. Sometimes the cooking bananas are then removed and then sesame seeds are scattered over them, dipped back in the oil and then set aside. So where to get them in Phuket? The best places are the Traditional Market areas...
