Here are some common reasons why your Caprese salad might be watery: Tomatoes: Overly ripe tomatoes release more moisture. Also, if you slice your tomatoes too thinly or unevenly, they can release excess juice into the salad. Mozzarella Moisture: Fresh mozzarella cheese can sometimes be quite moist. Make sure to pat it dry with a paper towel before assembling the salad. Excessive Olive Oil and or Balsamic Vinegar : using too much can lead to an overly liquid salad. Seasoning: Salt can draw moisture out of tomatoes. If you use salt, make sure to season your salad just before serving. If you notice excess moisture in your salad, you can gently drain it to minimize the liquid on the plate.
