Here's a simple rule of thumb: When using powdered pectin for cooked jam, add it to the strained juice or chopped fruit BEFORE heating. Next, bring the mixture to a full rolling boil (a boil that cannot be stirred down). THEN add the sugar. Bring to a boil again and boil for 1 minute.
Secondly, do you have to boil jam after canning? The jam mixture is boiled to reduce the liquid and bring the pectin to its gelling temperature. The bottles and lids are boiled to sterilize them as you said. The final water bath kills any bugs that were introduced while filling the jars. Additionally this boiling ensures a good seal on the bottles.

5 Ways to Thicken Homemade Jam

Use cornstarch, a thickening agent derived from corn, as a pectin substitute. Combined with sugar, a little cornstarch in the jam thickens as it cooks.Why is pectin added to jam?
Pectin. Pectin is a natural fibre found in plant cell walls and most concentrated in the skin of fruits. It is water-soluble and binds with sugar and fruit acid to form a gel.

Lemon juice doesn't actually contain any pectin (or it's very low in pectin), but the acidity works with the sugar to jell the pectin. Blueberries and peaches are both very low-pectin fruits, so I'm not sure that just using lemon juice would do much for jelling.How do you fix runny jam without pectin?
To Remake Without Added Pectin For each quart of jelly, add 2 tablespoons bottled lemon juice. Heat to boiling and boil for 3 to 4 minutes. Test for gel set to determine jelly doneness. Remove from heat, quickly skim off foam, and fill sterile jars, leaving ¼-inch headspace.Will homemade jam thicken as it cools?

Bring the jelly to a boil over high heat. For each quart of jelly, whisk in 1 tablespoon of pectin and stir constantly until the jam appears to thicken slightly.
