Classic Chocolate Milkshake

The chocolate milkshake is American engineering at its finest. Before the electric blender arrived in the 1920s, soda jerks built shakes by hand, working metal cups with the theatrical flair of cocktail bartenders. The result was a beverage so thick, so uncompromisingly rich, that it straddled the line between drink and dessert.

Somewhere along the way, we lost the plot. Fast food chains thin their shakes with stabilizers and air, producing something that flows through a straw without resistance. That is not a milkshake. That is a disappointment in a paper cup.

A proper chocolate milkshake should make you work for it. The straw should collapse slightly on your first pull. You should need a spoon to excavate the final inches from the glass. The chocolate flavor should be deep and slightly bittersweet, not the cloying sweetness of cheap syrup alone. This is that shake.

I've added Dutch-process cocoa to the formula because it provides something chocolate syrup cannot: complexity. The cocoa brings earthiness and depth while the syrup contributes glossy sweetness. Together, they create a chocolate experience worthy of the name.
