For the prettiest presentation, choose purple, orange, green, and red heirloom tomatoes. Cilantro lends the dressing peppery flavor and a subtle green hue. Vary the taste of the dressing by using basil and lemon rind. The dressing will keep for a couple of days in the refrigerator, so consider doubling the recipe to keep some on hand.
