Quality: Choose ripe, sweet berries with uniform color.
Procedure: Wash 1 or 2 quarts of berries at a time. Drain, cap, and stem if necessary. For gooseberries, snip off heads and tails with scissors. Prepare and boil preferred syrup , if desired. Add 1/2
cup syrup, juice, or water to each clean jar.
Hot pack -- For blueberries, currants, elderberries, gooseberries, and huckleberries. Heat berries in boiling water for 30 seconds and drain. Fill jars and cover with hot juice, leaving 1/2-inch
headspace.
Raw pack -- Fill jars with any of the raw berries, shaking down gently while filling. Cover with hot syrup, juice, or water, leaving 1/2-inch headspace. Adjust lids and process.
Processing directions for canning berries in a boiling-water, a dial, or a weighted-gauge canner are given in Table 1, Table 2, and Table 3.
