Howard, it's really easy! We buy a box of green apples at the markets, then cut them up into quarters. We use all of the apple except the stems. The cut up apples - peel, seeds, flesh and all - go into a very large pot, and we add enough water to float the apples. Cover this and bring it to a boil, making sure it doesn't boil over. Once it's boiling, you can drop the temperature down a bit so that it simmers - you want the pot to boil gently until the apples disintegrate and the flesh comes away from the peel and looks like chunky applesauce. For my large pot, that usually takes over an hour from when it starts to boil.
The next step is to strain it. We use a clean piece of calico (which I pour boiling water through to sterilise) to line a sieve or colander. Place the colander over a large pot/mixing bowl and pour everything through it. The most important thing is
not to press the mixture at all (or you'll get bitter and cloudy pectin). Just let it drip through at its own pace (usually at least four hours or overnight). When everything has drained through and the colander is no longer dripping, place the liquid in a large pot and bring it to a boil. You want to reduce the liquid by about 50% to make the final pectin.
There is a good test for pectin - you cool a tbsp or so in the fridge until it's cold (won't work if it's hot), then stir it into a little bit of rubbing alcohol (apparently methylated spirits will work as well). If the pectin is ready, it will coagulate and clump up when you try and pick it up with a fork. You are supposed to boil it until you get thick clumping, but we always get more of a soft gel, which drips a bit between the tines of the fork. It works fine for us, as it allows us a bit more flexibility with cooking times on the jams, and Pete likes his jams to be softly set.
Once the pectin is ready, you can either freeze it (though freezing slightly reduces the strength of the pectin), or you can pour it into sterile jam jars, and then boil the finished jars in a water bath for 10 minutes. This will ensure the pectin is ok for 6 - 12 months on the shelf.
Pete's basic jam method is add the pectin when boiling the cut up fruit, and then to add the sugar after the skins are softened. If you add the sugar too early, apparently the fruit skins can go quite hard. The amount of pectin he uses varies depending on the type of fruit (some have more pectin that others and therefore you need to add less). On average, I think he uses about 1 cup of pectin to each kilo (2.2 lb) of fruit. The nice thing about this is you don't have to be really careful with how long you boil the pectin in the jam, unlike commercial pectin that you're only supposed to boil for 5 minutes or so.
We put the leftover apple pulp through a food mill to get out the seeds, peels etc., then add brown and white sugar, lemon juice, cinnamon and allspice to it to make spiced apple butter. The mix is then baked in a roasting pan in the oven at 150C (300F), stirring every half an hour or so, until it becomes thick and brown (about 1.5 hours - any longer and you tend to get apple paste, which is also good). We spoon this into sterile jam jars and hot water process the sealed jars for 10 minutes. It makes a gorgeous apple butter to go into cakes, or as an accompaniment to roast pork or ham.
Below are the two articles which got us started. It's really a very rewarding process. We were able to make lots of pectin in July when apples were $5/10kilo box, and store it until December, when stonefruit was $1/kilo, at which time we used the pectin to make all the jams we made for Christmas gifts. Each 300ml jar of jam ended up costing us on average just over $1/jar, and that was only because the jar and lid cost $0.60! I posted about
jam making here a little while ago.
