We put two pears, two bananas (may already have ripened well), a small can of pineapple, a small can of mixed fruit, 1/4 liter of white rum and crushed ice in a blender. And off!
Pour into large glasses (0.6 liter capacity), insert slightly larger straws and let them taste good.
We got this cocktail served in Thailand. Thai whiskey is used there, we tried this with white rum and it tastes good too.
