2teaspoonscalcium water(this ingredient is included in Pomona's Pectin)
Instructions
Prepare boiling water canner. Heat 4 half pint jars in simmering water until ready to use, do not boil.
If needed, prepare calcium water by mixing ½ teaspoon calcium powder and ½ cup water in a jar with a lid.
Rinse and cut leafy tops off strawberries. Then cut into quarters, place in a bowl and mash strawberries.
In a separate bowl, mix 2 teaspoons Pomonas Pectin with the honey (or sugar).
Next, in a large saucepan, combine mashed strawberries, lemon juice, lemon zest, and 2 teaspoons calcium water. Stir and heat to a full rolling boil.
Add the pectin-honey mixture. Stir constantly to dissolve the pectin and bring to a full boil again. Boil for 1-2 minutes. Remove from heat.
Ladle jam into half pint jars leaving a 1/4 inch of head space. Wipe rim. Center lid on the jar. Screw on the band with until it is finger tip-tight.
Place jars in canner and ensure the jars have at least one inch of water above the tops of the jars. Bring to a boil and process for 10 minutes. Adjusting for altitude if needed (see note below).
Remove lid, turn off heat, wait 5-10 minutes then remove jars. After 24 hours remove rings, check seals, then store in cool, dark place. Makes 3 to 4 half pint jars of jam.
Notes
If you are at an altitude of above 1000ft above sea level, add 1 minute of processing time for canning. Each additional 1000ft adds 1 minute more. For example someone canning at 4000 ft above sea level should add 4 minutes to the processing time. For this recipe that would be 14 minutes total.
If you choose not to can the jars, they can be stored in the refrigerator for up to 3 weeks. Alternatively, you can store them in the freezer for up to 1 year
Pomonas Pectin is a special type of pectin that works well for low sugar jam and jelly recipes. There are no substitutes for it.
