Fill a shaker with ice. Add sake, vodka, Cointreau, and lemon juice.
Shake hard for 15–20 seconds.
Fill your glass with fresh ice and strain the mix into the glass.
Drizzle in the grenadine (it'll settle beautifully).
Top with soda, garnish with mint and lemon, and serve straight away.
Notes
Best Types of Sake for a Sake Fizz:1. Junmai Ginjo:Light, slightly fruity, and well-balanced—perfect for mixing.2. Junmai Daiginjo:A touch more refined and aromatic—ideal if you want the sake to really shine.3. Honjozo:Drier and crisper than ginjo styles—makes a great neutral base.
