Use ripe fruit to get the most pectin from it. Keep in mind that fruit naturally high in pectin tends to be acidic as well, which helps the fruit gel on its own when cooked. Ak No, a compote is simply the stewed puree of a fruit, apple, apricot, rhubarb, pear, plum, pineapple, etc etc with sugar added to taste. A compote is not a jam, or a jelly, so you are not trying to set it.
A compote is a perfect way to preserve all types of fruit for later use. It is generally kept in sealed sterilised jars. No added pectin required! Already a subscriber? Log in.

There are several reasons this can happen: Too little acid.
Low-acid fruits, such as peaches and pears, usually require a little added citrus juice to gel properly when using HM pectin. Too little pectin. Low-pectin fruits, like apricots, often require some added pectin to gel properly. Too little sugar. If using HM pectin without enough sugar, the sugar-acid-pectin matrix can be too loose to hold the liquid.
Wrong type of pectin. Low-sugar preserves made with HM pectin will not form a supportive matrix. But you can make sugary preserves with LM pectin as long as calcium is present to activate the gel.

For instance, apples have a higher amount of pectin than strawberries or raspberries. As you can see, some lower pectin fruits need a boost of pectin to properly set. This is especially true in many favorite jamming fruits like raspberries and strawberries.
Commercial pectin is commonly made from apple and citrus peels with dextrose to bind ingredients together. A commercial pectin may help speed up the cooking process, and perhaps cut back on the sugar a bit. You can find pectin in larger grocery stores near the canning supplies or with other baking ingredients.
You can also buy it online. Knowing the ins-and-outs of how pectin works will help you make a better jam. The type of fruit we choose to use has a huge impact not only on the flavor of the jam, but also the amount of pectin required to turn that fruit into jam or jelly.
Fruits that naturally contain plenty of pectin such as apples can be made into jelly without the use of added pectin. Others with low pectin such as strawberries and raspberries need a bit of help in the pectin department. Sometimes you can add high pectin fruits to low pectin fruits to increase the pectin factor.
We mentioned earlier that the ripeness of fruits also affects pectin content: riper fruits contain less pectin. Pectin is the natural thickening agent in fruit.
It needs the application of heat to activate. Pectin molecules have a negative charge which makes them repel one another and stick to water. Water is introduced when we prepare fruits chopping, cutting, and cooking. Naturally-occurring acid from fruits are also introduced during the cooking process. Acid helps to neutralize the negative ions of pectin so they can repel each other less and stick with water.
Many jam and jelly recipes call for the use of lemon peels or citric acid which helps level up the acidity of the mixture. A pH higher than 3. If you remember the pH scale, anything below 7 is acidic. Once sugar is added, the water molecules become attracted to the sugar which allows the pectin chains to get cozier with one another and form a web or network that when cooled, becomes jelly.
Sugar works by drawing water away from pectin and forming water-sugar bonds. The right amount of pectin-threads must get close enough to form a cross-bond to make gel.
Or commercially packaged pectin can be added to fruits low in natural pectin, like apricots, rhubarb, and strawberries. Note that just-ripe fruit contains the highest pectin levels. When fruit ripens further, its pectin content decreases as pectin turns to pectic acid. Don't be overly impressed by advertisements for "jam berries" that imply that overripe mushy fruit is optimal for preserving.
Though in very ripe fruit, flavors are fully developed, pectin is often past its prime. For best results, mix fully ripe fruit, which has the best flavor, with just-ripe fruit, which has the highest gelling power. Give jam and jelly making a try this season. You'll not only enjoy the process, but come winter, you'll treasure your results! How do they make jellybeans shiny?
