Slit the tops and peel the the plantains, with greased hands if necessary (sometimes they could get sticky/slimy).
Pour 4 cup water in a large bowl with 1 tsp salt and 1 tsp turmeric and stir.
Soak the plantains in this bowl for about 30 minutes.
Drain off the water and soak excess moisture with a kitchen towel.
Then, slice to medium thickness (with a mandolin, preferably).
Drop them in hot coconut oil in batches of one layer, to avoid clustering.
Make a turmeric water concentrate with 1 tsp turmeric, 1 tsp salt and 2 tbsp water.
Pour a tsp of this concoction into the frying chips (making sure to stay at a safe distance). This gives the chips the classic bright yellow colour.
Stir occasionally, and fry on medium flame.
Fry for about 10 minutes or until crispy but not golden brown.
Remove excess oil with a kitchen towel.
Enjoy plantain chips hot, with a cup of chai or store in an airtight jar for up to a month.
