The Strawberry Booster is a blended cocktail that was created by Clare Liardet and was first published in her book Dry: Delicious Handcrafted Cocktails & Other Clever Concoctions. It's essentially a cocktail-style strawberry smoothie, but instead of using milk, it’s made with a base of lemon juice and ginger syrup paired with a salt, strawberries, mint, and balsamic vinegar and topped with sparkling water. However, this variation adds in vodka and uses both honey and ginger syrup to tone down the spice.
Add lemon juice, vodka, honey syrup, ginger syrup, balsamic vinegar, strawberries, mint leaves, and sea salt to a blender.
Pulse until thoroughly mixed and frothy.
Fill a lowball glass with cracked ice.
Fine strain blended cocktail into lowball glass.
