Juicy plums and cucumbers mixed with fiery jalapeno chile attain just the right balance of sweet and spicy.
Stir together plums, cucumber, cilantro, lime juice, sugar, garlic, ginger, jalapeno, 1 teaspoon salt, and 1/4 teaspoon pepper in a bowl. Adjust flavor with lime juice and sugar if needed. Refrigerate for 1 hour before serving.
Salsa can be refrigerated for up to 1 day.
