- Pressure and Temperature: Maintain the correct pressure and temperature throughout the processing cycle.
Discussion:
Selecting Beans: Choose string beans that are fresh and tender. Avoid beans that are overly mature, wilted, or have any blemishes. Remove tough ends and strings before blanching.
Blanching: Blanching softens the beans and helps them retain their vibrant color. Place beans in a large pot of boiling water for 3-5 minutes, then immediately transfer them to an ice bath to stop the cooking process.
Packing Jars: Pack beans tightly into pint or quart jars, leaving 1-inch headspace. Add 1 teaspoon of salt to each jar for flavor and preservation.
Processing Time: Refer to USDA guidelines for processing times based on your altitude and jar size. Processing times vary depending on the size of the jars and the altitude.
Pressure and Temperature: Maintaining the correct pressure and temperature throughout the processing cycle is critical. Use a pressure cooker that is specifically designed for canning and follow the manufacturer's instructions.
Pressure Canning Process
Introduction: The pressure canning process involves filling jars with beans, processing them in a pressure cooker, and sealing them for long-term storage.
Key Aspects:
