Pectin, naturally found in fruit is vital to make your jam set. With low-pectin fruits like strawberries, help them along by either mixing with pectin-rich fruit like gooseberries or by using jam sugar (with added pectin and citric acid). When potting up, fill your jars to the brimful when the jam is still over 85°C.
What is jam production?

Should you stir while making jam?
Do no stir jam once boiling, but use a wooden spoon to check it is not sticking on the base of the pan. Stirring lowers the temperature and delays setting point being reached. It is wasteful to remove scum too often. Do it at the beginning and at the end.
Will my jam thicken as it cools?

Why isn’t my jam thickening?
Generally speaking, if your jam doesn’t firm up, you were short in pectin, sugar or acidity or didn’t get a hard boil. No matter how much you stir, you won’t get effective heat penetration in larger batches, so some pectin gets overcooked, while other pectin is not activated.
