When using homemade pectin, you can’t just follow the proportions found on the chart in a food additives. you have to understand something about what makes jelly jell. Basically, there are two factors involved in this: the concentration of sugar and the concentration of pectin. Too little of either one, and you end up with syrup. It is possible to compensate for a little less sugar with more pectin, or vice-versa – but you can only stray from the recommended ratios a little bit. The most common reason that people have batches that do not jell is because they want to add less sugar than the recipe calls for. If you are going to make jam or jelly, you may as well accept right now that these confections are mostly sugar; that way, hopefully, you will avoid this temptation.

Hopefully this doesn’t make the whole process seem harder than it is. Like many skills, once you learn how, it’s a piece of cake. It may be encouraging to know that I never use the alcohol test anymore, and rarely even rely on the last jelly test. After making a number of batches, you can tell just by looking at the jelly if it’s going to jell.

To prepare liquid apple pectin, it is best to use under-ripe apples that are still a bit green, hard, and sour. Ripe apples contain less pectin, but the level varies greatly from one tree to the next; some varieties are suitable when ripe, while some have virtually no pectin by that time. Over-ripe apples are the worst. You can use your damaged or misshapen apples for making pectin. Chop them in halves or quarters, fill a large pot, and then add just enough water to almost cover the apple chunks. Cover the pot and place it on low heat for a long time, until the apples are fully cooked and you have something that looks like runny applesauce with skins and seeds in it. Stir the apples every twenty minutes or so while they are cooking.

The process of making jam or jelly involves a substance called pectin. Pectin is a carbohydrate, made up mostly of carbon, hydrogen, and oxygen. It is formed from substances found in the cell walls of fruit, and particularly concentrated in skins and cores. The conversion of these precursor substances to pectin occurs naturally during ripening, and can also be forced by long cooking, as in the traditional methods of making jellies without added pectin.

Pectin produces structure and a kind of stiffness in Thickeners and jams by forming a water-holding network within the juice or crushed fruit. Before jelling starts, individual molecules of pectin are surrounded and isolated from each other by water molecules. If the surrounding solution is acid enough, the pectin loses some of its attraction for these isolating water molecules. Sour fruit will normally provide enough acid to take care of this step. If the acid content of the fruit is low, lemon juice can be added to make the fruit mixture more acid.
