pound tomatoes (about 3 medium) or 2 pints cherry tomatoes
shallot, peeled and minced
tablespoons sherry vinegar, plus more to taste
teaspoon red-pepper flakes (optional)
teaspoon kosher salt (Diamond Crystal), plus more to taste
teaspoon black pepper
cup extra-virgin olive oil
- Heat a broiler to high. Place the tomatoes on a sheet pan and broil until the skin is charred and peeling, about 6 minutes. Flip and char the other sides until the tomatoes are soft and begin to release some of their moisture, about 5 minutes. If using cherry tomatoes, blister without turning until the tomatoes char, collapse and release their moisture, about 10 minutes.
- When the whole tomatoes are cool enough to handle, transfer them to a board and coarsely chop. (Skip this step if you used cherry tomatoes.) Transfer the tomatoes with their juices to a medium bowl. Add the shallot, sherry vinegar, red-pepper flakes, if using, and the salt and pepper. Stir in the olive oil. Taste and add more vinegar and salt if necessary.
- Use immediately or refrigerate in an airtight container for up to 2 days. Serve as a dressing over cooked leafy greens, green salads, grain salads, roasted or grilled vegetables, meat and fish.
