How much pectin for 24 cups of apricots?

To calculate the correct amount, you'd need to know the desired stiffness and the sugar concentration of the jam you're making, but as a rule of thumb you'd need around 1 to 1.5 ounces (28 to 42 grams) of pectin powder for 24 cups of apricot.

Remember to follow the recipe you are using carefully, as the pectin amount can vary depending on the type of pectin and the specific fruit used.
