Sally's Rhubarb Jam
12 cups rhubarb, cut into small pieces
2 1/2 cups sugar
1 1/2 teaspoon cinnamon
3/8 teaspoon cloves
3/8 cup lemon juice
Mix the rhubarb and sugar in a bowl, and let it sit in the refrigerator overnight to macerate.
Transfer the rhubarb/sugar mix to a stainless steel pan. Stir in the cinnamon, cloves, and lemon juice. Bring to a boil, boil for 20 minutes, then simmering until it's jam consistency. Stir often to keep it from scorching.
Pour into prepared pint or half pint jars. Process in a water bath, 10 minutes for half pints, 15 minutes for pints.
Makes about 4 pints; 7-8 half pints.
Note: this recipe has a LOT less sugar than most of the ones I've found. If you think it's too sour, you can add more.
