I've never had any luck adjusting jam after it's been prepared. You mighty backing up to the step where you added the pectin and continuing from there with more, but be prepared. It's not likely to work out the way you want. (either too soft or too firm)
Pectin. Pectin is a food-gum that comes from fruit that helps thicken jam when sugar is added.
Yes you can recook jam that did not set. Just Google "recooking jam" and you will see a number of Coop. Ext. sites and others that will show you the way. Happy jammin' Thom Foote Fairbanks, Alaska

PECTIN
sur-gel is a brand name. Pectin is the ingredient. Pectin is the ingredient used in jam making, it helps set the jam.
Rhubarb is low in pectin, jam may not set

No, pectin is not an animal product, it is an enzyme found in fruits and it is used to help boiled sugar set when making jam.
Pectin is inside fruits and it makes your jam become more "solid". Sometimes, when you prefer to use less sugar than the regular recipe (the same weight of fruit and sugar), you may add pectine to make your jam not so liquid. Ana Maria da Costa http://www.all-about-italian-food.com
Because of the pectin in it. It acts like a preservative.
I make approximately 100 cases of jam each summer, I am looking for a cheaper geling agent than store bought pectin.
If the p means pectin then you can add 1 green apple unpeeled while cooking the strawberry jam. For more details check how do make your own pectin. Good Luck!! Lilly
