This is an interesting take on the popular teh tarik drink in Malaysia. Usually the tea is served really hot.
Teh ice, which is just teh tarik with ice, often tastes diluted if you don’t drink fast enough as the hot tea leaves a layer of cold water at the top of the drink.
Teh tarik “air con” includes the ice on the outside so that it cools but doesn’t dilute your drink! I think it’s a great way to serve a drink that you want called yet retains the original flavour.
