Please note: We don’t recommend making jam or jelly with absolutely no sweetener. The final product is likely to be tart and bland. Sweetener, even in a small amount, brings out the flavor of the fruit.
If you want to try it, however, this is what you do: For 4 cups of mashed fruit or juice, use either ½ cup water or unsweetened fruit juice (if you’re using 2 or 3 teaspoons of pectin) or ¾ cup water or unsweetened fruit juice (if you’re using 4 teaspoons of pectin).
Make liquid pectin by measuring the correct amount of water or juice into a small sauce pan and bringing it to a boil. Put boiling liquid in cup for immersion blender, or in food processor, or in blender. Add pectin. It is very important to vent the lid (if there is one) to let steam out. Don’t use an enclosed blender that can’t be vented. Blend for 10 seconds, then stop and scrape down the sides so all pectin clumps are in or on the liquid. Blend for a full minute until all powder is totally dissolved.
Add the liquid pectin to the boiling fruit or juice mixture, which should already contain the calcium water and lemon juice (or lime juice or vinegar) if called for in the recipe. Stir while mixture returns to a full boil. If you taste your jam before jarring and it isn’t sweet enough, you can add however much sweetener you want at this point. Stir well and return mixture to a boil, remove from heat, jar and process according to the recipe sheet that comes with Pomona’s Pectin.
These instructions are also on the recipe sheet that comes with your box of Pomona’s Pectin – back side, upper left-hand corner.
