"At a retreat in the foothills of the Canadian Rockies, I sampled a marmalade combining rhubarb and raisins. I loved it so much that I went home and tried to duplicate it. I added the strawberries to make the marmalade even sweeter."
Finely grate orange and lemon peels; squeeze and reserve juices. In a large saucepan, combine peels, juices, sugar, rhubarb, strawberries and salt. Cook and stir over medium heat until sugar dissolves; add raisins. Bring to a full rolling boil; cook over medium heat until thick, about 5-10 minutes. Pour hot jam into hot jars, leaving 1/4-in. headspace. Adjust caps. Process for 10 minutes in a boiling-water bath.
