Apricot jam pectin, sugar, lemon juice, calcium, yield, and jars
How Much Pectin for Apricot Jam Calculator
Estimate the pectin needed for apricot jam from prepared fruit volume, fresh or dried apricot form, ripeness, pectin type, sugar plan, lemon juice, cook loss, jar size, and altitude.
Choose a real apricot jam starting point, then adjust the batch before you cook. The calculator keeps the pectin sizing tied to prepared fruit, not whole fruit weight.
Apricot Jam Batch Breakdown
Best for classic cooked apricot jam with full sugar.
Usually added after sugar for a bright, quick boil batch.
Better match for tart apricot flavor and lighter sweetness.
Uses calcium water and works with honey or very low sugar.

Making apricot jam require an understanding of the relationship between apricots, sugar, acid, and pectin. Because apricots does not contain enough pectin to create jam, an additional amount of pectin is require. The amount of pectin needing in the jam is not constant because the amount of pectin contained in the apricots vary with the ripeness of the apricots, the amount of sugar uses, and the amount of acid added to the jam.
The ripeness of the apricot will determines the amount of pectin needed to make apricot jam. Very ripe apricots will be soft and will readily release there juices. These apricots will require more pectin then firm apricots because firm apricots will retain their shape when make the jam.
How to make apricot jam set
Apricots should be weighed after the cook remove the pits as apricots and pits will weigh different than apricots alone. The amount of sugar in the jam will impact the amount of pectin required. Jam recipe with high levels of sugar will require less pectin than recipes with low amount of sugar.
To make apricot jam with less sugar, the cook will have to add more pectin to the jam, or use a low-sugar pectin product in place of regular pectin. The amount of lemon juice in apricot jam will impact the amount of pectin that is required to make the jam. Lemon juice contain the acid required to allow the pectin to coagulate and form the gel like texture required for jam.
Too little lemon juice will result in a jam that dont set properly and will be too loose for jam. Too much lemon juice will make the jam taste too sour. The natural acid content of apricots will change with the ripeness of the apricots so the amount of lemon juice require will change with the ripeness of the apricots.
The amount of time that apricot jam is boiled will change the amount of pectin that is required. If apricot jam is boiled for a short period of time, a jam that retain its water will be made and more pectin will be require. Boiling apricot jam for a longer period of time will allow the water in the jam to evaporate so a smaller amount of pectin will be required to make a jam of the proper thickness.
The altitude at which apricot jam will be stored will affect the way the jam set. Apricot jam will boil at a lower temperature at higher altitude. While altitude will not change the behavior of the pectin, it will change the time in which the jars of apricot jam must be process in a canner to ensure that the jam is safe to eat.
A pectin calculator will allow the individual to input the ripeness of the apricots, the amount of sugar that will be use, and the length of time that the jam will be boiled. The calculator will provide the amount of pectin that should be use in the apricot jam given these variable. If too much pectin is used, the apricot jam will become rubbery and taste like candy.
If not enough pectin is used, the apricot jam will not set and will remain liquid. The amount of pectin that is required for dried apricot is different than the amount required for fresh apricots. When dried apricots are rehydrated they will behave different in the jam.
Additionally, dried apricots require more acid than fresh apricots so that the apricot jam will not have a flat taste. Freezer jam is different from apricot jam that is boiled. For freezer jam the pectin must be a specific type of pectin.
Because jam that is made and stored in freezers do not require the heat to activate the pectin, the texture of the jam will be softer when it is set in the freezer as compare to apricot jam that is boiled. By tasting the apricot jam that is made it is possible to understand the adjustments that can be made to the apricot jam recipes to be use in the future. If the apricot jam is too runny it will be necessary to increase the amount of sugar or pectin that is used to make the apricot jam.
If the apricot jam is too stiff it will be possible to use less pectin or boil the jam for a shorter time period. Through understanding how each of these ingredient interact with one another it is possible to control the outcome of the apricot jam recipe.
