Shiro Plum Jam

Step 1

Peel the fruit and put into a stainless steel pot. Bring to a simmer for 5 minutes. The fruit is much easier to peel if it has been frozen and thawed first.

Step 8

Use a large spoon to remove any foam. Place the pot on a burner that is on the lowest setting just to keep the jam warm while you work pouring the warm liquid into the jars.
