Distilling is a way to purify a mix of liquids by heating it up and cooling it down. But just 'cause you can distill some plants and fruits to make booze, it don't mean you can distill any ol' thing. Bananas might have some sugars in 'em, but it ain't enough to make a decent amount of hooch just by fermentin' 'em. But you can make banana wine if you add some sugar and yeast to mashed-up bananas and let it ferment. And that ain't distillation, that's just mixin' stuff up and lettin' it sit.
