Test thickness on a plate: ladle into sterilized mason jars and seal; refrigerate until ready to use.
Place berries and water into the mixing bowl and heat for 10 minutes at 100F Reverse speed 2 with the Varoma over the hole in the lid to catch any possible overflow
Add sugar to berry mixture in the mixing bowl and heat for 5 minutes at Varoma at Reverse speed 2 with the simmering basket over the hole in the lid
NOTE: be sure that berries reach boiling for 2 minutes
In the "old days", when you and I were young, these berries were made into vast batches of jam and canned fruit to be preserved over Winter. Now, they are fast frozen freshly picked, and small batches of jam are made, as needed.
The amount of water is used only to loosen and sweat the berries. As the berries are frozen, just 2 tablespoons. This is not an error.
The amount of sugar to berries in a jam is usually 1:1 but this is perfect at 1 cup sugar to 3 cups berries to our taste.
