Strawberry Rhubarb Raspberry Mixed Berry Jam (Printable)
Vibrant, tangy-sweet jam combining strawberries, rhubarb, raspberries, and mixed berries. Perfect for toast, yogurt, or gifting.
# 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 such as blueberries or blackberries, fresh or frozen
→ Sweetener
05 - 2½ cups granulated sugar
→ For Setting
06 - 2 tbsp lemon juice freshly squeezed
07 - 1 package 1.75 oz fruit pectin powder
# Method:
01 - Combine strawberries, rhubarb, raspberries, and mixed berries in a large non-reactive pot. Mash lightly with a potato masher to release juices.
02 - Stir in lemon juice and fruit pectin. Mix thoroughly and let the mixture stand for 5 minutes to activate the pectin.
03 - Place the pot over medium-high heat. Bring the mixture to a boil while stirring frequently to prevent sticking.
04 - Add all the sugar at once and stir until completely dissolved. Return to a full rolling boil and boil hard for 1 to 2 minutes to reach setting point.
05 - Remove from heat and skim off any foam from the surface with a spoon. Carefully ladle hot jam into sterilized jars, leaving ¼-inch headspace.
06 - Wipe jar rims clean, seal with lids, and process in a boiling water bath for 10 minutes for long-term storage. For immediate consumption, skip the water bath.
07 - Allow jars to cool completely at room temperature. Refrigerate opened jam and consume within 3 weeks for best quality.
# Insider Tips:
01 -
- The rhubarb adds this incredible tang that cuts through all that sweetness, making every spoonful interesting instead of just sugary
- Adding raspberries to the usual strawberry-rhubarb combo was a game changer, giving the jam this deep, almost wine-like complexity
02 -
- That rolling boil phase needs to be aggressive and continuous, not a simmer or gentle bubble, or your jam might not set properly
- Skimming the foam is not just cosmetic, it makes the jam clearer and prevents weird air pockets from forming in your jars
03 -
- Clean your jar rims with a damp paper towel before sealing, any sticky residue will prevent a proper seal
- Listen for the pop sound as jars cool, that little ping tells you the vacuum seal worked perfectly
