General Instructions

Preparing and Using Syrups
Measures of Water and Sugar for 9-pint load (or 4-quart load)
Type of syrup Sugar Water
10% (very light) 1/2 cup 4 cups
20% (light) 1 cup 4 cups
30% (medium) 1 3/4 cups 4 cups
40% (heavy) 2 3/4 cups 4 cups
50% (very heavy) 4 cups 4 cups
Procedure: Heat water and sugar together. Bring to a boil and keep hot until ready to use. Adding syrup to canned fruit helps retain flavor, color, and shape. It doesn’t prevent spoilage of these foods.

Canning Fruits Without Sugar: Select fully ripe but firm fruits of the best quality. Prepare fruit for hot packs as described above but use water or regular unsweetened fruit juices instead of sugar syrup. Juice from the fruits being canned is best. Blends of unsweetened apple, pineapple, and white grape juice are also good for filling over solid fruit pieces. Adjust head spaces and lids and use processing recommendations given for regular fruit.

1Altitude Adjustment: For altitudes of 1,001–3,000 feet, add 5 minutes to processing time.

2Antidarkening Solution: Mix one teaspoon or 3000 mg of ascorbic acid into one gallon of water. Commercially prepared mixes of ascorbic are also available in supermarkets. Follow the manufacturer’s directions. Hold small batches of fruit in the solution until ready to use. Drain thoroughly.
