Following tested canning procedures and guidelines from reputable sources, such as the USDA’s Complete Guide to Home Canning, is crucial.
Calculating the Yield: Bushels to Jars
The number of jars a bushel of tomatoes fills depends on several factors, including the size of the tomatoes, the desired product (sauce, crushed, whole, etc.), and the size of the jars being used. A bushel of tomatoes typically weighs around 53 pounds and contains approximately 20-25 pounds of usable tomato flesh after sorting and trimming.
Factors Influencing Yield
- Tomato Variety and Size: Larger tomatoes with more flesh will generally yield more product per tomato than smaller ones.
- Product Type: The yield can vary significantly depending on whether you’re making sauce, canning whole tomatoes, or preparing crushed tomatoes. Sauces, for example, require cooking down the tomatoes, which concentrates them and can significantly reduce the volume.
- Jar Size: The standard sizes for canning jars are 4 oz, 8 oz, 16 oz, and 32 oz. The size of the jar will directly impact how many jars are filled from a bushel of tomatoes.
Estimating Jar Yield
As a rough estimate, a bushel of tomatoes can yield:
– For Canned Tomatoes (whole, crushed, or diced): 20-30 quarts (16 oz jars), assuming about 2.5-3 lbs of tomatoes per quart after preparation.
– For Tomato Sauce: 40-60 pints (16 oz jars), considering that the cooking process reduces the volume of the tomatoes, and about 1.5-2 lbs of fresh tomatoes might yield one pint of sauce.
Step-by-Step Guide to Canning Tomatoes
Canning tomatoes is a multi-step process that involves preparation, cooking (for sauces), filling jars, and processing the jars to ensure they are safely sterilized and sealed.
Preparation
Preparation involves washing, sorting, and trimming the tomatoes. For whole or crushed tomatoes, a blanching step may be included to loosen the skins, which are then removed.
Cooking (for Sauces)
For sauces, tomatoes are cooked down with minimal water to create the desired consistency. This step can significantly reduce the volume of the tomatoes.
Filling and Sealing Jars
Jars are filled with the prepared tomatoes or sauce, leaving the recommended headspace. Lids and rings are applied, and the jars are then processed in a boiling water bath or pressure canner, depending on the product and altitude.
Importance of Headspace and Processing Time
Leaving the correct headspace and adhering to the recommended processing time are critical for ensuring that the jars are properly sterilized and sealed, preventing spoilage and foodborne illness.
Conclusion
The journey from a bushel of fresh tomatoes to filled jars on your pantry shelf is rewarding and filled with possibilities. By understanding the factors that influence yield and following safe canning practices, you can enjoy your home-preserved tomatoes throughout the year. Whether you’re aiming to make sauces, can whole tomatoes, or prepare crushed tomatoes, the process is a labor of love that connects us with our food, our heritage, and the joy of preserving the seasons’ bounty. With practice and patience, you’ll find that the art of canning tomatoes is not just about filling jars but about creating a legacy of flavor and tradition.
