Notes
Yuzu juice: If you cannot find fresh yuzu, bottled yuzu juice works perfectly. Look for unsweetened 100% yuzu juice for the best flavour balance.Spirit choice: This cocktail works beautifully with both vodka and gin. Vodka creates a cleaner, citrus-forward drink, while gin adds botanical depth.Balance the flavour: Yuzu can vary in tartness. Taste and adjust the sweetness by adding a little more simple syrup if needed.Chill everything: For the best texture and flavour, chill your glass and ingredients before mixing. This keeps the martini crisp and refreshing.Shake properly: Shake with ice for at least 10 to 15 seconds to fully chill and slightly dilute the drink for a smooth finish.Glassware: Serve in a chilled martini glass for a classic presentation, or use a coupe glass as an alternative.Garnish ideas: Try a strip of lemon peel, yuzu zest, or a thin slice of citrus to enhance aroma.Make it ahead: You can pre-mix the liquid ingredients and store them in the fridge for a few hours. Shake with ice just before serving.
