A note on using nonfat milk, skim milk, rice milk, soy milk, almond milk: The flavors that make spices taste delicious are all aromatic compounds. Aromatic compounds are made of molecules that contain a structure known as a benzene ring, meaning they dissolve best in alcohols or fats. You may have noticed this when making drinks, that adding a twist of lemon to a martini adds significantly more flavor in a shorter amount of time than adding a twist of flavor to a glass of water. Similarly, if you make this chai with a non-fat milk, you won’t extract as many flavors from the spices as if you make it with a milk that has some fat. Coconut milk might be a vegan alternative, as it contains relatively high fat.
