Campari tomatoes are typically sold on the vine. They are prized for their sweet flavor.
Look for tomatoes with a nice sheen. It should not have blemishes on it. The color can be red or red tinged with green. If you would like to store them, put them in a place away from sunlight at room temperature. You can place them stem side down if they are not done ripening yet.
These tomatoes are great for snacking. You can eat them with a little bit of mozzarella as the flavors will compliment each other. Camparis can also be used to add more flavor to sauce. They also go great baked with a bit of cheese on top.
