Start heating and stir in Pacific Pectin Mix.
Heat to a boil and continue boiling while stirring for about 1 minute to dissolve pectin.
Slowly stir in sugar in two parts, so temperature of fruit doesn't drop.
Heat to boilng and cook to 219° F (below 1000 feet elevation, 217.9° F to 1500 feet, 216.1° F to 2500 feet)
Stop heating. Skim and pour. Close lids tightly and invert jars to sterilize, about 3 minutes. Then turn jars upright and let cool.
NOTE: For larger batches, multiply weight figures by desired increase. Use same procedure, but cook to 61-65 brix, depending on the desired sugar level. To replace lemon juice with citric acid, figure 5.5% of the lemon juice as Anhydrous Citric Acid. In the above recipe, the lemon juice may be replaced by 0.3 oz. (9.4g) citric acid dissolved in 5 ½ fl oz. of water.
