Introduction to Plum Tomatoes
Plum tomatoes, also known as Roma or Italian tomatoes, are a variety of tomato that is esteemed for its elongated shape, dense flesh, and low water content. These characteristics make plum tomatoes ideal for canning, sauces, and other preservation methods. Their flavor profile is often described as sweeter and less acidic than other tomato varieties, which adds to their popularity in culinary applications.
Why Preserve Plum Tomatoes?
Preserving plum tomatoes offers several advantages. It allows you to:
– Enjoy your harvest throughout the year, even when fresh plum tomatoes are out of season.
– Save money by using your preserved tomatoes in a variety of dishes, from pasta sauces to soups and stews.
– Ensure that the effort you put into growing your tomatoes does not go to waste.
– Explore different culinary traditions and recipes that rely on preserved tomatoes.
Preparation for Preservation
Before diving into the preservation methods, it’s crucial to prepare your plum tomatoes. This involves:
– Selecting tomatoes that are ripe but still firm. Avoid using overripe or rotten tomatoes, as they can spoil the entire batch.

Using Dehydrated Tomatoes
- Dehydrated tomatoes can be stored in airtight containers for up to 6 months.
- To rehydrate, simply soak the dried tomatoes in hot water or broth until they soften.
Additional Preservation Methods
Besides canning, freezing, and dehydrating, there are other creative ways to preserve plum tomatoes, such as making sun-dried tomatoes, tomato jam, or pickled tomatoes. Each of these methods offers a unique flavor profile and texture, and they can add variety to your preserved tomato collection.
Making Sun-Dried Tomatoes
Sun-dried tomatoes are made by dehydrating plum tomatoes in the sun or using a dehydrator. The process is similar to dehydrating, but the resulting product is often more intensely flavored and chewier. To make sun-dried tomatoes:
– Prepare the tomatoes as for dehydrating.
– If using the sun, place the tomato slices on a wire rack or a sheet pan, cover them with cheesecloth to keep insects away, and leave them in direct sunlight for 3 to 7 days, or until they are dry and chewy.
– If using a dehydrator, follow the manufacturer’s instructions for temperature and time.
Preserving Sun-Dried Tomatoes
- Store sun-dried tomatoes in olive oil to enhance their flavor and prevent spoilage.
- Keep them in the refrigerator to prolong their shelf life.
