Canning jars
Threaded, heat-processing jars hold food and a fitted lid during a tested canning process; jar size and process belong to the specific recipe.
Modern method
Pumpkin and pineapple Autumn Glory compote: Cupboard: exact Bernardin formulation and water-bath process.

This is an important exception to the idea that pumpkin can never be water-bath canned. A specifically formulated mixture of pumpkin, pineapple, lemon and dried fruit can be processed that way. It does not establish that an arbitrary pumpkin jam or chutney is safe. Bernardin explicitly instructs readers not to change its ingredients, quantities, jar size or process.
The University of California Master Food Preservers' 2025 presentation identifies the recipe as tested and uses bottled lemon juice. The version below follows that bottled-juice choice while retaining Bernardin's measured Canadian volumes and 500 ml jar format.
Approximately four 500 ml jars. Measure the prepared produce; “one pineapple” is a buying estimate, not a substitute for the specified volume.
These are the source's volume measures, including sugar and dried fruit, not invented gram conversions. The pumpkin purchase estimate is about 1.4 kg whole fruit, but preparation losses vary.
Elevation, feet: 0–1,000; Time for the specified jars: 25 minutes.
Elevation, feet: 1,001–3,000; Time for the specified jars: 30 minutes.
Elevation, feet: 3,001–6,000; Time for the specified jars: 35 minutes.
Elevation, feet: 6,001–8,000; Time for the specified jars: 40 minutes.
Elevation, feet: 8,001–10,000; Time for the specified jars: 45 minutes.
The altitude schedule is given by UC Master Food Preservers. Do not extrapolate above the published range.
Keep successfully sealed jars in a cool, dark place and plan to use within one year for best quality. Refrigerate after opening. If a jar has not sealed after cooling, treat it as a refrigerated preparation, not a cupboard preserve.
This is a preserved component, not a complete dish. Its inclusion is useful because it provides a documented shelf-storage option for pumpkin pieces in an acidified sweet preserve. Do not increase the pumpkin, reduce the fruit or juice, substitute a different dried fruit, omit sugar, or puree the contents while retaining this canning schedule.
