Canned plum tomatoes are a staple ingredient in many cuisines, particularly in Mediterranean and Italian cooking. These delicious and versatile tomatoes have been a cornerstone of many recipes for decades, and their popularity shows no signs of waning. But what exactly are canned plum tomatoes, and what makes them so special? In this article, we’ll delve into the world of canned plum tomatoes, exploring their history, production process, nutritional benefits, and culinary uses.
A Brief History of Canned Plum Tomatoes
The concept of canning tomatoes dates back to the early 19th century, when Napoleon Bonaparte’s chef, Nicolas Appert, developed a method for preserving food in glass jars. However, it wasn’t until the late 19th century that canned tomatoes became widely available. The first canned tomatoes were made from a variety of tomato called the “San Marzano,” which was grown in the Campania region of Italy. These tomatoes were prized for their sweet-tart flavor and low acidity, making them ideal for canning.
The Rise of Plum Tomatoes
In the early 20th century, a new variety of tomato emerged: the plum tomato. Plum tomatoes are characterized by their oval shape, dense flesh, and sweet flavor. They are also lower in water content than other tomato varieties, making them perfect for canning. The plum tomato quickly became the preferred choice for canning, and its popularity has endured to this day.
The Production Process
So, how are canned plum tomatoes made? The production process is quite fascinating and involves several steps:
Harvesting
Plum tomatoes are typically harvested in late summer and early fall, when they are ripe and ready to be picked. The tomatoes are carefully selected and sorted to ensure that only the best quality tomatoes are used for canning.
Washing and Sorting
The tomatoes are then washed and sorted to remove any stems, leaves, or debris. This is an important step, as any impurities can affect the quality of the final product.
Peeling and Chopping
The tomatoes are then peeled and chopped to remove the skin and any excess liquid. This helps to prevent the tomatoes from becoming too watery during the canning process.
Cooking and Packing
The chopped tomatoes are then cooked in large vats to create a rich, flavorful sauce. The sauce is then packed into sterilized cans, which are sealed and heated to kill off any bacteria.
Pasteurization
The final step is pasteurization, which involves heating the cans to a high temperature to kill off any remaining bacteria. This ensures that the canned tomatoes are safe to eat and will last for a long time.
