The Lemon Pepper Fizz And Lemongrass Vodka

Liquid Intelligence
This drink is very refreshing. Lemongrass is sometimes difficult to work
with because long infusions bring out a detergent like flavor. My rapid iSi
technique eliminates this problem. Note that this recipe asks for a lot of
lemongrass: it’s the only way to get the spirit to balance the way I like it to.
The whipper will be almost full of lemongrass. The lemongrass infusion
should be used fresh—within a day or two. Keep it in the freezer and it
should last a week.

I carbonate this cocktail to highlight the freshness of the lemongrass. Although I use a carbonation rig to add bubbles, you could use a
Sodastream, or in a pinch the same whipper you used for infusing. The
cocktail calls for Black Pepper Tincture and clarified lemon juice. If that’s
too big a hassle for you, carbonate the base cocktail and then add regular
lemon juice and a couple grinds of fresh black pepper. I won’t tell.
