We saw the recipe for the Plum Splet in an episode of Love is Like a Cocktail, a cute anime series about a bartender who makes cocktails for his wife. We didn’t know what a “splet” was, so we did a little digging and discovered that it was a mistranslation of ume supureddo, or “plum spread.”
The drink doesn’t taste much like a spread; it’s tart and bright rather than jammy or rich. Given that, and the fact that so many folks are searching for a “plum splet” recipe like we were, we’ve kept the mis-translated name.
We did adjust the recipe, which originally called for a way-too-tart 1:1 ratio of plum wine to lemon juice. If you have a very sweet plum wine, you may wish to increase the amount of lemon juice just a bit.
