Yuzu, the lemony citrus fruit that’s a staple in Japan, provides the essential flavor and aroma for Yuzuri, a new Japanese liqueur. The whole fruit — peels, juice and pulp — steeps for a month in a spirit made from rice. The liqueur is then lightly sweetened. The result is almost colorless, with a flavor that’s citrusy, hinting of lemongrass and more tart than sweet. I’d keep it on the bar to add a new dimension to lemony cocktails like a sidecar or a whiskey sour: Yuzuri, $37.99 for 750 milliliters, Hi-Time Wine Cellars, Costa Mesa. Calif., hitimewine.net.
