Murcia is a region in SE Spain, on the Mediterranean coast, where tomatoes are a major crop. The traditional way to make the dressing is using a mortar and pestle, but the blender simplifies the process.
- On a cutting board, smash the garlic cloves with the flat side of a butcher knife. Work a little salt into the garlic with the edge of the knife to make a paste. Place in a blender.
- Peel and coarsely chop one tomato and add it to the blender. Pulse the tomato together with the garlic, until well blended.
- Add the vinegar, pepper, 1/2 teaspoon cumin seeds, and paprika to the blender and blend until smooth.
- Add the olive oil and blend to mix well with the rest of the ingredients.
- Cut the remaining tomatoes crosswise into 1/2-inch slices. Arrange them on a serving platter single-layered or overlapping as little as possible.
- Pour the tomato vinaigrette over the sliced tomatoes and sprinkle with the remaining cumin seeds.
- Serve at room temperature.
