Using a mandolin slicer, slice the banana slices in batches into hot oil, and try not to overcrowd the pan.
When they are almost done, add a few teaspoons of turmeric water into the oil. You need to be very careful at this stage as the oil will start to splutter. You will also hear a sizzling sound. The chips will be ready when the sizzling sound stops.
Remove the banana chips from oil, and drain them on a paper towel.
