My jam is too liquid!
Whatever your tried, your strawberry jam is way too liquid. The reason is that it simply lacks of cooking, so cook your jam longer. You can add a bit of agar to help with the thickening process. Make sure you use jam sugar because it contains pectin, a gelling agent. To ensure you have a good texture at the en dof cooking, drop a bit of jam on a plate, if it sticks, it’s done!
