Ingredients:
- 2 lbs fresh strawberries, hulled and quartered
- 1 lb fresh rhubarb, trimmed and diced into 1/2 inch pieces
- 1 tbsp lemon juice
- 4 cups granulated sugar
- 1.75 oz powdered fruit pectin
- 1/4 tsp salt
Instructions:
- Wash the strawberries and rhubarb thoroughly. Hull the strawberries and cut them into quarters; slice the rhubarb into small, uniform 1/2 inch pieces.
- Place the prepared strawberries, rhubarb, lemon juice, and salt into the slow cooker.
- Add the granulated sugar and stir until the fruit is evenly coated.
- Cover with a lid and set the slow cooker to LOW for 8 hours (or HIGH for 4 hours). Stir gently every 2 hours to ensure sugar is dissolved.
- Perform the plate test by dropping a small spoonful of jam onto a frozen plate; if it wrinkles when pushed after 30 seconds, it is set.
- Whisk in the powdered fruit pectin during the final 30 minutes of cooking according to package instructions.
- Ladle the hot jam into sterilized jars, leaving 1/4 inch of headspace. Seal tightly and cool at room temperature.
