The mozzarella in your Caprese pasta salad is central to its charm, so keeping it fresh and flavorful is key: Proper Storage: Store it in the fridge in its original liquid until you're ready to use it. Room Temperature: Let the mozzarella come to room temperature before adding to the salad. Cold mozzarella can be rubbery and flavorless. Drain Well: Ensure that mozzarella balls are well-drained to prevent excess moisture from watering down your salad.
