I think I have another post about this, but here goes with my latest version.

We have a prolific harvest this year, so jam and other preserving is under way. Because there are several punnets of raspberries waiting to cook, I need more pectin. So I made another batch from the windfalls from the apple trees. I cut all the bruising and bugs out, and cut the pieces into 2cm chunks. Then squeezed 2 lemons and put the juice and the squashed peel into a saucepan with the apples with water to just about half way up.
Cook them until they are soft and squash them into a mush. Then strain through a muslin overnight.

I am tempted to squeeze more juice out, but that will make the pectin cloudy, it’s up to you.
Now check for the set of the pectin. You can put small, equal amounts of sugar and pectin into a saucepan, stir, boil and rest. But I out the two ingredients into a ramekin and cook in the microwave for 40 seconds on full power. Take it out and stir. Repeat.

Whichever cooking method to have used, drop a blob onto a chilled saucer and if it sets into a soft lump, the pectin is ready to bottle. Otherwise, return it to the saucepan and boil to reduce then retest.
Bottle the pectin in a sterilised bottle, (use the microwave for the glass bottle, but boil the metal lid).
Once cooked, store in the fridge for up to 4 weeks. Can also be frozen in a plastic container.
I use about a third to half a cup to 500g fruit when making soft fruit jam, but always test for the set before bottling jam.
Happy jam making.. 🙂
