1 ripe tomato
1 sprig of cilantro, chopped
1 teaspoon lime juice
1 teaspoon umeboshi plum vinegar (also called ume plum vinegar)
1 sprig of shiso (Japanese herb in the mint family)
1. Use a very sharp knife to chop the tomato into small pieces (grape-sized or smaller) and place in serving bowl.
2. Mix cilantro with the lime juice and umeboshi plum vinegar
3. Drizzle dressing over tomato
4. Sprinkle chopped shiso leaf on top -- a Shiso flower on the top can make for a very nice touch.
Source of recipe: This recipe was inspired by an appetizer they sometimes serve at Oishii Boston, a fancy gourmet sushi place. They call it a "ceviche" but really it is just a chopped-up tomato with a really nice dressing -- it should also work well if a little bit of chopped up cucumber is added.
