Just a thought that I had recently. In many parts of the world, people cook bananas when they are unripe, and in other parts of the world, people eat “dessert” bananas (e.g. Cavendish types) when they get yellow but not yet spotty. Do kids today know what a ripe banana is?
Ripe is when the starches have converted to sugars as much as possible but there is not yet any significant fermentation. In Cavendish subgroup bananas, this generally occurs when the peel has numerous brown spots on it. Some bananas (plantains) are totally black when ripe. Some don’t change colour after turning yellow, and ripeness must be judged by softness…
