Use fresh, ripe heirloom tomatoes, good-quality extra-virgin olive oil and aged balsamic if possible. While classic caprese salads use beefsteak tomatoes, I like to step it up a notch and use juicy, heirloom tomatoes.
Slice the tomatoes and mozzarella cheese into ¼”-thick slices. Arrange the mozzarella, heirloom tomatoes, cherry tomatoes, and basil leaves on a large platter.
Drizzle olive oil and balsamic vinegar over the top. Season with salt to taste. Serve at room temperature.
Notes
Salt the tomatoes before assembling the salad and let them sit for a few minutes. This draws out some of their juices and concentrates their flavor while creating a delicious tomato dressing that mixes with the olive oil and balsamic vinegar.
