🍽 Servings & Time
Makes: 2 to 3 small jars (about 3 cups)
Total Time: 45 minutes
🔬 Why This Recipe Works (Quick Science)
Strawberries are naturally high in sugar and water. Rhubarb is lower in sugar but full of pectin, a natural thickener. Cooking them down together draws out the water and activates the natural pectin, thickening the jam without needing to add any.
📋 What You’ll Need
- 3 cups strawberries (hulled and chopped)
- 2 cups rhubarb (sliced thin)
- 1 ¾ cups granulated sugar
- 1 tablespoon lemon juice
- 1 teaspoon vanilla extract (optional)

👩🍳 Tools You’ll Need
- Medium saucepan
- Wooden spoon or silicone spatula
- Potato masher (optional)
- Measuring cups and spoons
- Mason jars or airtight containers
💡 Pro Tips
- Don’t walk away—jam can boil over fast.
- Use a wide saucepan for quicker thickening.
- Stir often to avoid burning the bottom.
- For a chunkier jam, mash lightly; for smoother, mash more.
- Let it cool before judging thickness—it sets up more as it chills.
🔄 Substitutions & Variations
- Swap raspberries or blueberries for strawberries
- Add a pinch of cinnamon or fresh grated ginger
- Use honey or maple syrup for a natural sweetener (reduce amount)
🕒 Make Ahead Tips
- You can prep the fruit a day before—just store it in the fridge.
- Jam lasts up to 3 weeks in the fridge or 6 months in the freezer.
👣 Instructions
Step 1: Prep the Fruit
Hull and chop the strawberries. Slice the rhubarb into small, thin pieces so it breaks down faster.

Step 2: Combine in Pot
Add strawberries, rhubarb, sugar, and lemon juice to a saucepan. Stir everything together over medium heat.

Step 3: Cook Until Bubbly
Let the mixture heat up. It will start to bubble and break down. Stir often—this takes about 15-20 minutes.

Step 4: Mash and Simmer
Use a spoon or masher to break up the fruit. Lower heat and simmer until thick—about 10–15 more minutes. Stir often.

Step 5: Add Vanilla (Optional)
Turn off the heat and stir in vanilla extract for an extra cozy flavor.

Step 6: Cool and Store
Let the jam cool slightly, then spoon it into clean jars. Once cool, seal and store in the fridge.

🧊 Leftovers & Storage Tips
- Keep in the fridge for up to 3 weeks.
- Freeze in freezer-safe jars for 6 months.
- Always use a clean spoon to keep it fresh.
⚠️ Common Mistakes
- Undercooking: If it’s too runny, just cook a bit longer.
- Overcooking: It gets too thick and sticky—pull it off once it coats the spoon.
- Not stirring enough: Can scorch the bottom—stir often.
- Not prepping the fruit evenly: Uneven sizes can lead to uneven texture.
🧺 What to Serve With
- Fresh sourdough or toast
- Swirled into Greek yogurt
- On top of pancakes or waffles
- In thumbprint cookies
- Spoonful with sharp cheese on a cracker
