Ingredients
700gplumschopped and stoned
400gsugargranulated or jam
4tbspchia seeds
Juice of 1 lemon
300mlcold water
2tspground cinnamon
Instructions
Put into a large pan with the water and cook gently for about 20 minutes until the plums are soft but not disintegrated.
Add the sugar, chia seeds, cinnamon and lemon juice and stir until the sugar has dissolved.
Bring to the boil and boil rapidly until setting point has been reached. This is when the jam has a jelly like texture and is starting to stick to the side of the pan (see notes). This can take as little as 10 minutes if using jam sugar, and up to 40 if using granulated.
When setting point has been reached, leave to cool for 20 minutes before ladelling into jars
Recipe Notes
Notes: jam doesn’t have to be fully set if chia seeds are yet to expand and absorb some of the excess liquid. If the mixture has thickened and plums have disintegrated, remove from heat and test 20 minutes later to check if it’s set.
