TheFoodening Blog: plum ginger jam ready to eat |
3 lbs Italian plums (dark purple skin, yellow flesh), pit removed
2 1/2 c organic granulated sugar
2 tsp kosher salt
1/4 c fresh lemon juice
2 tbsp ground ginger
1/2 c whiskey or bourbon, any plain variety
Directions
1. Wash and quarter the plums, removing the pits. Place plums in a large bowl and mix with 1/2 c sugar, salt, and lemon juice. Store in refrigerator overnight.
2. Cook plums, its juices, and remaining sugar in a heavy-bottomed pot over medium heat for 15 minutes. If you're going to strain out the skins, do so at this point, otherwise use an immersion blender and purée it all smooth. Stir frequently or the jam will burn. Add ginger powder and cook for an additional 15 minutes.
As you boil the plums with the sugar, don't be alarmed by the not-red color this produces before using the immersion blender.
3. Add the whiskey, if using, and boil for an additional 3 minutes.
4. Process using hot jam in hot sterilized jars/bands/lids in a hot water bath for 15 minutes.
