Take one big raw banana/plantain. Trim both the edges. Then slit the rims and peel off the skin from bananas.

Slice the bananas as thin as possible. Use a slicer to make the job easy. The slices should be very thin so that it gets dried up easily.

Transfer the banana slices in a plate, arrange it and sun dry it for 2-3 days.

After sun drying the banana slices, transfer to a dry mixer jar and blend it to a smooth powder.

Then sieve the powder thoroughly with a sieve. Discard the seeds. Cool it down and store in an airtight container.
