Yujacha Sour — Japanese Whisky, Yuzu bitters, Lemon juice, Honey syrup, Yuzu preserves, Egg white
This drink is delicious! I've tried it both with Nikka Coffey Grain, and with the cheaper Suntory Toki, and it was fantastic both ways! It's definitely a crowd-pleaser, but it's still complex enough for more seasoned cocktail fans. Highly recommended if you've got the ingredients.
