Peel the skin of banana and keep ready.
Take water in a bowl, mix turmeric powder and salt.
Heat oil in a deep bottomed pan.
Take a slicer and slice raw banana over the oil directly keeping the flame medium.
Fry till it turns slightly golden, sprinkle the turmeric mixture little by little as needed for each batch.
You need to be very careful at this stage as the oil will start to splutter. You will hear a sizzling sound.
The chips will be ready when the sizzling sound stops.
Remove the chips from oil and drain them on a paper towel.
Cool and store in an airtight container.
