1. Simmer all the ingredients together in a medium-size saucepan over low heat for 10 minutes, stirring occasionally.
2. Test the jam for firmness (agar's thickening effect varies according to its fineness) by putting a large metal spoon with a small amount of jam in the freezer for a couple of minutes until the jam is chilled. If the jam is the right thickness, your recipe is done. If the jam is too watery, stir in more agar, simmer the jam for another 5 to 10 minutes, and test it again. If the jam is too thick, stir in some fruit juice or water and test it again immediately.
3. Let the jam cool to room temperature.
