Place all ingredients into TM bowl and cook 25-35 min/Varoma/speed 1 with simmering basket on top of lid in place of the MC (cooking time will vary depending on whether you are using fresh or frozen strawberries).
Check the consistency of the jam by placing a spoonful onto a cold plate. If it wrinkles up when pushed, the jam is ready. If not, cook 10 min/Varoma/speed 1 at a time and check after each time period, up to 30 minutes more, until it has reached the consistency that you like. (This is an edit; please see comments below.)
Pour into sterilised jar and allow to cool before serving.
