Oriental Plum Sauce — Bernardin
Ingredients
- 10 cups (2500 ml) prepared plums, about 4 lb (1.8 kg)
- 2 cups (500 ml) firmly packed brown sugar
- 1 cup (250 ml) granulated sugar
- 1 cup (250 ml) cider vinegar
- 3/4 cup (175 ml) finely chopped onion
- 2 tbsp (25 ml) finely chopped green chili peppers
- 2 tbsp (25 ml) mustard seed
- 1 tbsp (15 ml) salt
- 1-2 cloves garlic, minced
- 1-2 pieces (each 1/4 x 1 inch / 0.5 x 2.5 cm) gingerroot, minced
- Pit and finely chop plums. Measure 10 cups (2500 ml); set aside.
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
Directions
- Place 6 clean 250 ml mason jars on a rack in a boiling water canner. Cover jars with water and heat to a simmer (180°F/82°C). 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. Combine sugars, vinegar, onion, mustard seed, chili peppers, salt, garlic and gingerroot in a large stainless steel saucepan. Bring to a boil; add plums.
- Return mixture to a boil; boil gently, stirring occasionally, about 1 3/4 hours or until thick and syrupy. Ladle sauce into a hot jar to within 1/2 inch (1 cm) of top of jar (headspace). Using nonmetallic utensil, remove air bubbles and adjust headspace, if required, by adding more sauce.
- 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 sauce.
- 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, 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
