Notes
Plantains should be very ripe with the skin at least 50% black, unless you prefer a more dense cake then feel free to use plantains that are a bit less ripe.
Although baking is often used in modern versions, traditionally it is often steamed or cooked like a pancake (dosa-like) in the more egg rich versions.
This cake is often enjoyed as an Iftar (meal to breakfast) snack during Ramadan.
