Best way to serve plum sake??!
Answers: and what plum sake do you recommend?
If you can afford to spend a little more money, get a bottle of Prosecco (Italian bubbly) and mix it with the plum sake (3:1 sake to prosecco ratio). It's a great aperitif.
Otherwise, you can drink it straight, chilled.
I like it at room temp, and the only one I really like is the one P.F. Chang's serves. So good!
