This jam reverses the usual strawberry-rhubarb ratio and put rhubarb in the driver's seat. Swirl it into Greek yogurt, use it as a topping for vanilla ice cream, or spread it over banana bread. Its gorgeous, pale pink hue would make a perfect Mother's Day gift.

Note:Pomona's Universal Pectin is available at most supermarkets. If you can't find it, substitute Ball Flex Batch Low or No-Sugar Pectin.

Ingredients

  • 2 cups sugar
  • 2 1/2 teaspoons Pomona's Universal Pectin
  • 1 3/4 pounds rhubarb, diced
  • 2 cups quartered strawberries
  • 3 tablespoons freshly squeezed lemon juice
  • 2 teaspoons calcium water
  • 1/2 teaspoon unsalted butter

Directions

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

  2. Combine the rhubarb 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 strawberries in a food processor or blender. You should have 1 cup.

  3. Measure the stewed rhubarb. You should have about 3 cups. Return the rhubarb and the pureed strawberries to the saucepan. Add lemon juice, calcium water, and butter, 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.

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