Mash raspberries and verify that you have 2/3 cup.

Add sugar and pectin and mix well to dissolve.

If texture seems grainy, microwave for 30 seconds and continue stirring.

Transfer mixture to mason jar place lid and screw on lid.

Place in freezer until ready to use or in refrigerator if you will use now.
