1. Peel the bananas. Place them into iced water.
2. Slice the bananas into even slices. Place back in the water as you slice them. Add the turmeric powder.
3. Leave in the water for 10 minutes. Then drain and place on a clean tea towel to retain the moisture.
4. Heat the oil. Drop in a few slices at a time to deep fry (don't overcrowd the oil). Use a slotted spoon to add and retrieve the slices.
5. Repeat until all slices have been fried.
6. Drain by placing the slices on kitchen paper towel.
7. Let cool. Once cooled, they can be served or stored. To store, place in an airtight container, such as a glass container or resealable bags.
