- Low moisture content: Compared to slicing tomatoes, plum tomatoes have less water, making them ideal for sauces and pastes. Less water translates to less cooking time needed to achieve the desired consistency.
- Few seeds: The relatively small number of seeds in plum tomatoes further enhances their suitability for processing.
- Concentrated flavor: The flavor of plum tomatoes is often described as slightly sweet and subtly acidic. This balance of flavors intensifies during cooking.
- Firmness: Their firmness allows them to hold their shape well during cooking.

Tomato Varieties Similar to Plum Tomatoes
Several tomato varieties share similar characteristics with plum tomatoes, making them excellent substitutes or alternatives for specific culinary applications.
San Marzano Tomatoes: The Gourmet Choice
Often considered the gold standard for Italian sauces, San Marzano tomatoes are a type of plum tomato originating from the volcanic plains near Mount Vesuvius in Italy. They are characterized by:

While San Marzano tomatoes are often more expensive and may be harder to find than Roma tomatoes, their exceptional flavor makes them a worthwhile investment for discerning cooks. Be cautious of imitations, as many canned tomatoes are labeled “San Marzano” without being authentic. Look for the official DOP (Denominazione di Origine Protetta) seal to ensure you are getting the real deal.

What characteristics define a paste tomato, and why are they often compared to plum tomatoes?
Paste tomatoes are characterized by their elongated, oval shape, thick walls, and relatively low water content, making them ideal for sauces, purees, and canning. Their meaty texture and fewer seeds contribute to a concentrated tomato flavor when cooked down.
The comparison to plum tomatoes stems from their shared shape and dense flesh. Plum tomatoes are a specific type of paste tomato known for their rich flavor and suitability for processing. While all plum tomatoes are paste tomatoes, not all paste tomatoes are plum tomatoes. There are variations in size, flavor, and disease resistance within the paste tomato category.
Besides Roma, what other tomato varieties are considered similar to plum tomatoes and good for making sauce?
Several tomato varieties share similarities with plum tomatoes and excel in sauce making. San Marzano tomatoes are highly regarded for their sweet flavor and thin skin, making them a premium choice for Italian sauces. Amish Paste tomatoes are another excellent option, known for their large size, meaty texture, and slightly tangy flavor.
Other notable alternatives include Principe Borghese, a smaller, drier paste tomato often sun-dried, and Opalka, a Polish heirloom with a distinctive banana-like shape and rich flavor. These varieties offer diverse flavors and textures to cater to different preferences in sauce making. Experimenting with these options can lead to unique and delicious results.
How does the water content of paste tomatoes like plum tomatoes affect sauce consistency?
Paste tomatoes, including plum varieties, are prized for their lower water content compared to slicing tomatoes. This characteristic directly impacts the consistency of homemade sauces. With less water to evaporate, the sauce thickens more quickly and requires less simmering time to reach the desired texture.
The reduced water content also contributes to a more concentrated tomato flavor. Excess water in the sauce can dilute the flavor, requiring more seasoning and longer cooking times. Using paste tomatoes allows for a richer, more intense tomato taste in the final product, creating a more flavorful and satisfying sauce.
Are plum or other paste tomatoes suitable for eating fresh, or are they best used in cooking?
While primarily used for cooking, plum and other paste tomatoes can be eaten fresh, although their texture and flavor differ from traditional slicing tomatoes. Their dense flesh and lower water content result in a less juicy bite, and their flavor can be more acidic or less sweet than some other varieties.
However, some people enjoy the firmer texture and concentrated flavor of paste tomatoes in salads or sandwiches. Roasting them can also enhance their sweetness and make them more palatable for fresh consumption. Ultimately, the suitability for eating fresh depends on personal preference.
What are the common diseases that affect paste tomatoes, and how can they be prevented?
Paste tomatoes, like other tomato varieties, are susceptible to various diseases, including early blight, late blight, and blossom-end rot. Early blight causes dark spots on leaves, while late blight can rapidly destroy the entire plant. Blossom-end rot, caused by calcium deficiency, results in a dark, leathery spot on the bottom of the tomato.
Prevention strategies include choosing disease-resistant varieties, ensuring proper soil drainage, providing adequate calcium levels, and practicing crop rotation. Using fungicides as a preventative measure and promptly removing infected foliage can also help control the spread of disease. Consistent monitoring and early intervention are crucial for maintaining healthy plants.
How do the growing conditions for paste tomatoes, like plum tomatoes, differ from those for slicing tomatoes?
While the general growing requirements are similar, paste tomatoes like plum tomatoes often benefit from specific conditions compared to slicing tomatoes. They generally prefer well-drained soil with consistent moisture, but they can tolerate slightly drier conditions due to their lower water content.
Support systems like cages or stakes are essential, especially for heavy-yielding varieties, to prevent fruit from touching the ground and reduce the risk of disease. Additionally, paste tomatoes tend to be determinate varieties, meaning they produce all their fruit at once, making them ideal for processing large quantities.
Can you save seeds from plum tomatoes and other paste tomatoes to grow future generations of plants, and are there any considerations?
Yes, you can save seeds from plum tomatoes and other paste tomatoes, but it’s important to understand the type of tomato you’re saving seeds from. If you are saving seeds from a hybrid variety, the resulting plants may not be true to type, meaning they might not exhibit the same characteristics as the parent plant.
For best results, save seeds from open-pollinated or heirloom paste tomatoes. To save seeds, select ripe, healthy tomatoes, scoop out the seeds and pulp, ferment them in water for a few days to remove the gelatinous coating, then rinse and dry them thoroughly before storing them in a cool, dark place.
