Frozen bananas can taste like ice cream for a few reasons: Natural sugars: Bananas contain natural sugars, particularly fructose, which contributes to their inherent sweetness. When frozen, the natural sugars become concentrated, intensifying the sweetness. Texture: Freezing bananas alters their texture and makes them firmer. When blended or pureed, the frozen bananas turn creamy and smooth, similar to the texture of ice cream. The high water content in bananas also contributes to the desirable texture when frozen. Starch content: Bananas contain starch, which gets converted into sugars as they ripen. Overripe bananas, with more developed starches, tend to have a sweeter taste. When frozen and blended, the starches break down further, resulting in a smoother consistency and enhanced sweetness. Mouthfeel: The combination of the natural sugars, texture, and cold temperature creates a creamy, pleasant mouthfeel that is reminiscent of ice cream.
