Strawberry Rhubarb Raspberry Berry Jam (Printable)

A vibrant, tangy-sweet jam combining strawberries, rhubarb, raspberries, and mixed berries for a delicious twist on classic preserves.

# What you'll need:

→ Fruits

01 - 2 cups strawberries, hulled and chopped
02 - 1½ cups rhubarb, sliced (fresh or thawed from frozen)
03 - 1 cup raspberries
04 - 1 cup mixed berries (blueberries, blackberries), fresh or frozen

→ Sweetener

05 - 2½ cups granulated sugar

→ For Setting

06 - 2 tablespoons lemon juice, freshly squeezed
07 - 1 package (1.75 oz / 49 g) fruit pectin powder

# Directions:

01 - In a large non-reactive pot, combine strawberries, rhubarb, raspberries, and mixed berries. Mash lightly with a potato masher to release juices.
02 - Stir in lemon juice and fruit pectin. Mix well and let stand for 5 minutes.
03 - Place the pot over medium-high heat and bring the mixture to a boil, stirring frequently.
04 - Add sugar all at once and stir to dissolve completely. Bring back to a full, rolling boil, then boil hard for 1-2 minutes.
05 - Remove from heat. Skim off any foam with a spoon. Carefully ladle hot jam into sterilized jars, leaving ¼-inch headspace. Wipe rims, seal with lids, and process in a boiling water bath for 10 minutes, if storing long-term.
06 - Allow jars to cool completely. Refrigerate opened jam and use within 3 weeks.

02 -
  • Use a stainless steel or enamel pot since aluminum can react with acidic fruits

  • Skimming off foam before jarring gives you a clearer, more jewel-like jam
  • Adding vanilla or cinnamon before filling jars creates a sophisticated variation
