A yogurt cocktail might sound crazy if you're new to soju. But yogurt soju is really popular in Korea and all over Asia. Both yogurt and soju go well with the fiery aspects of Korean cuisine, so it makes sense to combine them into a delicious cocktail.
Take one part of soju, one part of yogurt drink and 1 part of lemon soda (7 up or sprite will do). Shake everything with ice and pour into a nice glass. Enjoy!
