WASH THE RHUBARB AND SLICE into pieces 1/4-inch thick. If the stalks are wide, cut them in halves or thirds lengthwise, first. Finely chop the grated ginger with the garlic and chile. Place all the ingredients in a non-corrosive pan, bring to a boil, then lower the heat and simmer until the rhubarb is broken down and is the texture of a jam, about 30 minutes. Store refrigerated in a glass jar. Makes 1 Cup
