Nutrition Information

There is nothing like a Maine-grown tomato during summer! From mid-July to late September, Maine residents can enjoy the freshness and flavor of locally grown tomatoes picked at peak ripeness. Though technically a fruit, the tomato is treated as a vegetable. Originally tomatoes were yellow, but today most of those produced in the United States are red. In addition to the standard-sized, round tomatoes, there are other varieties, such as plum, pear-shaped, and cherry tomatoes.

Tomatoes are rich in vitamins A and C and fiber, and are cholesterol free. Field- or vine-ripened tomatoes available in summer are higher in vitamin C than the greenhouse tomatoes that are available in fall and winter. Fresh tomatoes contain more vitamin C than cooked or canned. Tomatoes contain lycopene, an important carotenoid, which may help protect against prostate cancer and heart disease.


Select firm, fragrant fruit with full, bright color. Avoid bruised, blemished, soft, or hard fruit. Tomatoes should yield to gentle pressure.


Keep ripe tomatoes at room temperature: above 55 degrees is recommended. Do not refrigerate under-ripe fruit. Tomatoes will ripen better out of sunlight. Once tomatoes are red and slightly soft, they will keep a day or two at room temperature. Refrigerate only if you want to keep them longer.

Wash carefully. Peel if you desire. To peel, remove stem core and dip tomatoes in a large quantity of boiling water for 30 seconds; then dip in cold water, and the skins will be easy to remove. When using tomato pulp in a recipe, it is a good idea to remove the skin and seeds first, as they toughen when cooked.

Raw: This is the best way to enjoy a freshly picked tomato! Add fresh tomatoes to salads, nachos, scrambled eggs, sandwiches, or macaroni and cheese. You can even make an uncooked tomato sauce. Peel and seed a tomato, mash it into a pulp, and add minced onions, a little red wine vinegar, and chopped herbs. Or try chilled or hot fresh tomato soup—the canned variety doesn’t compare!

Broil: Halve large tomatoes, sprinkle with pepper and a little oil, or try parmesan cheese and oregano. Cook four to five minutes under the broiler at 500 degrees until heated through. These are excellent served as a side dish.

Bake: Bake tomato halves, either plain or stuffed with toppings, in a 400°F oven for eight to fifteen minutes.

Microwave: Cook in a covered dish. One pound will take three to four minutes. Use in casseroles, stews, soups, and sauces.
