A classic vanilla milkshake is simplicity in a glass. In its most basic from, there are only two ingredients in a vanilla milkshake: vanilla ice cream and milk. It makes sense, then, that you should buy the highest quality ingredients you can. To truly make the best vanilla milkshake in the world, look beyond the bargain ice creams (which could be full of chemicals and fake flavorings) and splurge for something that has been made using only real ingredients.The milk is the other half of the milkshake equation. Just like with the ice cream, you should buy the best milk you can afford. Full fat milk is also essential for a creamy, rich finish, so now is not the time to buy one percent — it’s a milkshake for crying out loud!The recipe below is a great starting place, but feel free to alter the ratio of milk to ice cream to suit your personal preference — more milk for a thinner shake and less for something a bit thicker.Bon appétit!If you like your milkshakes with a grownup twist, click here for 6 Delicious Alcoholic Milkshakes.
