The minimal ingredients in this salad allow tomatoes to shine through. Besides our star, salt is the most important element because it draws out the juices to leave the tomato with more concentrated flavor. The resulting pink-hued juices mingle with the shallot, olive oil and lemon juice to create a dressing that is so good, it is reason enough to make this salad. Use up every drop by dipping into it with grilled bread, or pour it over braised beans, grilled fish or roast chicken. While tomato salads are often dressed with vinegar, lemon juice is more gentle, working behind the scenes to help tomatoes taste like their brightest selves.
