Remove the scum from the surface. but leave the scum around the edges. Repeat the process 3 times.
Microwave 3 times for 5 minutes each and it's done! Fill a 12 cm ramekin with the jam. Once cooled, chill in the refrigerator until thickened.
Story Behind this Recipe
This is a strawberry jam I make every year. I've often made it in a pot, but making it in the microwave takes only a short time and has the best color. 1 package only needs three 5 minute heating sessions. It can be stored in the freezer.
Make in a large bowl. The reason for heating it in 3 sets of 5 minutes is so that you can remove the scum. It doesn't take a lot of fuss, but if you remove the scum, you'll have a lovely jam.
