If the idea of tomatoes and watermelon together sounds odd to you, this dish will be a revelation. There is a saying that what grows together goes together, and in this case it is true. If you think of tomatoes as a fruit, which they are botanically, this combination makes more sense. Seasonality, however, is the key. I make this salad only in the summer, when tomatoes, watermelon, and cucumbers are at their peak of flavor. Rich, creamy Hass avocadoes are included to lend a nice contrast of flavor and texture. I always toss this salad together before serving, but for the photo opposite I was inspired to create a painstaking mosaic of the ingredients. If you're so inclined, feel free, but don't say I didn't warn you—it takes a lot of time.

　　

Ingredients

Serves 4 to 6

　　3 or 4 small to medium heirloom tomatoes, in assorted colors, cored and cut into 3/4-inch chunks

　　1 small English or regular cucumber, peeled, seeded, and cut into 3/4-inch cubes

　　1 cup 3/4-inch-cubed yellow or red seedless watermelon flesh

　　1 Hass avocado, halved, pitted, peeled, and cut into 3/4-inch cubes

　　1 tablespoon chopped mixed fresh herbs, in any combination: basil, tarragon, chives, and cilantro

　　1/4 teaspoon coriander seed

　　3 tablespoons extra virgin olive oil

　　3 tablespoons aged balsamic vinegar

　　Kosher salt and freshly ground black pepper

　　1 freshly ground black pepper

　　

Step 1

In a bowl, combine the tomatoes, cucumber, watermelon, avocado, and herbs. In a spice grinder, grind the coriander seeds to a fine powder. Add the ground coriander to the tomato mixture and toss gently.

　　

Step 2

In a small bowl, whisk together the olive oil, balsamic vinegar, and salt and pepper to taste. Pour over the tomato mixture and toss to coat evenly. Taste and adjust the seasoning before serving.

　　To Drink

　　If you asked a group of sommeliers which white-wine variety they most often recommend to guests in their restaurants, the majority would answer Riesling, one of the world's greatest wine grapes. Rieslings can vary in style, but all are delicate, acidic, and fruity (often tasting of apricot and peach). Look for a California German-style Riesling that is dry, light, and slightly sweet for serving with this salad, such as the Navarro from Anderson Valley or an Esterlina from Mendocino.
