Make a batch of no pectin strawberry rhubarb jam with just strawberries, rhubarb, lemon juice, and sugar! This fruit-forward spread is sweet, tart, and perfect for summer.
In large saucepan, stir together 5 1/2 cups rhubarb, 2 1/2 cups strawberries, 2 1/2 cups sugar, and 1 Tablespoon lemon juice over medium heat. As soon as it starts to bubble, reduce heat to medium low or low. You will want a few bubbles but not a rolling boil.
Simmer,stirring occasionally, 1 hour, or until the jam has thickened and a digital thermometer reads 220°F.
Carefully pour hot jam into 5 half-pint sterilized jars (*see note), leaving 1/4-inch room at the top. Place lids on top and secure the ring bands. Let cool, untouched, 24 hours to set. Store in the refrigerator up to 2 weeks.
