Classic Peach Preserves — Bernardin
Ingredients
- 4 cups (1000 ml) peeled, 1/8in slices of peaches
- 6 cups (1500 ml) granulated sugar
- 4 tbsp (60 ml) lemon juice
- 1 pouch (85 ml) BERNARDIN® Liquid Pectin
Equipment
- 1 Boiling-water bath canner with rack
- 1 Large stainless or enamel preserving pot
- 1 Canning jars with two-piece lids
- 1 Headspace and bubble tool
- 1 Jelly or candy thermometer
Directions
- In a large, deep stainless saucepan, alternately layer peaches and sugar. Cover and let stand at room temperature for 4 to 6 hours. Place 8 clean 250 ml mason jars on a rack in a boiling water canner; cover jars with water and heat to a simmer (180F/82C). Set screw bands aside.
- Keep jars hot until ready to use. Preheating Bernardin® lids is not advised. The sealing compound used for our home canning lids performs better at room temperature than it does pre-heated in simmering water (180°F). Simply wash lids in hot, soapy water, dry, and set aside until needed.
- Preheating can lead to less vacuum being achieved during water bath canning, and to buckle failures during pressure canning. Add lemon juice and 1/2 tsp (2 ml) butter to reduce foaming (optional) to marinated peach-sugar mixture. Over high heat and bring mixture to a boil, stirring constantly.
- Immediately stir in liquid fruit pectin. Return to a full rolling boil that cannot be stirred down and boil hard 1 minute, stirring constantly. Remove from heat and skim foam. Ladle hot preserves into a hot jar to within 1/4 inch (0.5 cm) of top of jar (headspace).
- Using nonmetallic utensil, remove air bubbles and adjust headspace, if required, by adding more jam. Wipe jar rim removing any food residue. Centre sealing disc on clean jar rim. Screw band down until resistance is met, then increase to fingertip tight. Return filled jar to rack in canner.
- Repeat for remaining jam. When canner is filled, ensure that all jars are covered by at least one inch (2.5 cm) of water. Cover canner and bring water to full rolling boil before starting to count processing time. At altitudes up to 1000 ft (305 m), process - boil filled jars - 10 minutes.
- When processing time is complete, turn stove off, remove canner lid, wait 5 minutes, then remove jars without tilting and place them upright on a protected work surface. Cool upright, undisturbed 24 hours; DO NOT RETIGHTEN screw bands. After cooling check jar seals.
- Sealed discs curve downward and do not move when pressed. Remove screw bands; wipe and dry bands and jars. Store screw bands separately or replace loosely on jars, as desired. Label and store jars in a cool, dark place. For best quality, use home canned foods within one year.
- Processing: At altitudes up to 1000 ft (305 m), process - boil filled jars - 10 minutes - 10 minutes.
- Altitude-adjusted processing table: At altitudes up to 1000 ft (305 m), process - boil filled jars - 10 minutes
