Plan a tested water-bath canning recipe: match jar size and altitude, prepare equipment, maintain the complete boiling process, and check cooled jar seals.
Open a tested canning recipe for the exact food and preparation. Build a batch card with its source, ingredient amounts, pack style, jar size, required acidification and processing table. A pH reading alone cannot supply that process.
Find the elevation of the actual canning location and select the recipe table’s matching row. Convert meters to feet if needed. Prepare the canner, rack, jars and closures according to the recipe and equipment instructions; copy its headspace and jar preparation directions.
Load the prepared jars and establish the water coverage specified by the canner guidance. Start the recipe’s timer after the water reaches a full boil. Maintain boiling for the entire altitude-adjusted process. If boiling stops, restore it and restart the full process time.
Use the canner instructions to remove jars upright with a jar lifter. Let them cool undisturbed, then check seals and label each batch with its food, recipe and date. Consult the linked seal guidance promptly if a jar is unsealed.
Loading your checklist…
Copy these details from the chosen recipe and your actual setup. This card helps keep one batch tied to one process.
| Record | Check against |
|---|---|
| Food, cut and pack style | Exact preparation in the recipe |
| Jar size and headspace | Recipe instructions |
| Site elevation and process time | Matching row in the recipe’s table |
| Boiling interruptions and seal outcome | Actual batch observations |
Read the full loading, boiling, water-level and jar-removal procedure before starting.
Use the published cooling and seal checks, including its options and time limits for a jar that fails to seal.
Check the equipment requirements for the method specified by the recipe.
Write the food, pack style, jar size and elevation beside the processing time so a number cannot be detached from its conditions.
Set aside a stable surface and the jar-handling equipment before heating the batch.
