Cinnamon & walnut frappuccino

This modern, American-style iced coffee is a true cavalcade of textures and flavours. The oiliness of the walnut and the milk fat together create an incredibly creamy emulsion, whilst the ice slush provides refreshment. Cinnamon not only spices but also makes the drink taste sweeter, so it is just as enjoyable with less sugar.

Instructions

1

Brew the coffee well in advance and chill it. Even better if you freeze the coffee in an ice cube tray.

Tip: Coffee aromas are heat-sensitive; rapid cooling 'locks in' the flavours and prevents souring [Slowing oxidation].
2

Put the ice, milk, cold coffee, walnuts, cinnamon, salt, and sweetener into the blender.

Tip: Sugar syrup or honey mixes immediately even in the cold, unlike granulated sugar which would crunch under your teeth [Solubility].
3

Blend until the ice is completely crushed and the drink has a thick, slushy consistency.

Tip: The fine particles and oil content of the walnuts help stabilise the mixture, giving a creamier mouthfeel [Emulsification].
4

Whip the cold cream. Pour the drink into a glass, crown with whipped cream, and sprinkle with a little extra walnut.

Tip: The layer of fat from the whipped cream coats the tongue, softening the astringency of the coffee and walnut [Flavour masking].

Recipe FAQ

Why did my drink separate?
The ice slush and liquid naturally separate over time. Fattier milk or cream helps slow this process down.
Can I use hot coffee?
Not recommended, as it melts the ice too quickly and the drink will be watery instead of slushy.
