One of my favorite uses of the whipping siphon is to create foams for drinks and cocktails. It's a great way to add to the presentation of any drink and get your guests talking. It's also often as easy as blending one of the drink's ingredients with a thickener such as xanthan gum or Ultra-Sperse to give it some body.
This recipe is a refreshing take on blueberry lemonade that changes the ubiquitous summer drink into a modernist creation your friends will love. It is a light blueberry froth dispensed on top of a glass of lemonade. The blueberry foam slowly filters into the drink, changing the flavor of the lemonade the longer you drink it. It is a quick recipe to make and is a great way to elevate a common drink.
If you can't find blueberry puree or blueberry juice, it is easy to make your own. In a blender, combine blueberries with some water or orange juice and puree until it becomes very smooth. Simply strain the puree to remove pieces of blueberries and the puree is ready to use.This is a very versatile base recipe. You can replace the blueberry juice with any berry juice or other flavorful liquid. You can also use different bases than lemonade such as ginger ale, lime soda, or club soda. Feel free to experiment and see what works best for you.
