Rhubarb Raisin Marmalade

Directions

1. Finely grate orange and lemon peels; squeeze and reserve juices. In a Dutch oven, combine the peels, juices, sugar, rhubarb, strawberries and salt. Cook and stir over medium heat until sugar is dissolved; add raisins. Bring to a full rolling boil; cook over medium heat until thick, about 5 minutes.
2. Remove from the heat; skim off foam. Carefully ladle hot mixture into hot pint jars, leaving 1/4-in. headspace. Remove air bubbles; wipe rims and adjust lids. Process for 10 minutes in a boiling-water canner.
