Millionaire's Cherry Rhubarb Jam Recipe

Whisk the sugar and pectin in a medium bowl and set aside.

Combine the rhubarb, vanilla bean, and 1/2 cup water in a large saucepan. Bring to a boil, then reduce the heat, cover, and simmer just until the rhubarb breaks down, 10 to 12 minutes. Meanwhile, puree the cherries in a food processor or blender. You should have 1 cup.

Measure the stewed rhubarb. You should have 3 cups. Discard the vanilla bean. Return the rhubarb and the pureed cherries to the saucepan. Add lemon zest and juice and calcium water and bring to a boil over medium-high heat. Add the sugar-pectin mixture and return the fruit mixture to a boil, stirring constantly. Boil hard for one minute.

Remove the pot from the heat and skim any foam from the surface of the jam with a cold metal spoon. Stir in the Grand Marnier. Ladle the jam into hot sterilized jars and process them in a hot water bath for 10 minutes.
