Semi-dried tomatoes, also known as sun-dried tomatoes, are ripe tomatoes that have been partially dehydrated to concentrate their flavor. The process involves removing the moisture from the tomatoes, usually by sun drying or using a dehydrator. This results in tomatoes that are chewy and slightly shriveled, with an intense, sweet-tart flavor. Semi-dried tomatoes can be used in a variety of dishes to add a burst of rich tomato flavor. They are often used in salads, pasta dishes, sandwiches, pizzas, and antipasto platters.
