Here’s a classic Berry Jam Recipe you can make at home and store in canning jars. It works for strawberries, raspberries, blueberries, or a mixed berry combination.
Ingredients (makes ~4 half-pint jars)
- 4 cups fresh or frozen berries
- 4 cups granulated sugar
- 2 tbsp lemon juice (freshly squeezed)
- 1 packet (1.75 oz) fruit pectin (optional, for thicker jam)
Equipment
- Large pot
- Wooden spoon or heatproof spatula
- Canning jars with lids
- Water bath canner or large pot for boiling jars
Instructions
1. Prepare the Jars
- Wash jars and lids in hot soapy water.
- Keep jars warm in a pot of simmering water until ready to use.
2. Cook the Jam
- In a large pot, mash berries lightly with a potato masher.
- Stir in sugar and lemon juice; let sit for 10–15 minutes.
- If using pectin, sprinkle it over the fruit and stir to combine.
- Bring mixture to a rolling boil over medium-high heat, stirring constantly.
- Boil for 1–2 minutes, or until jam reaches desired thickness.
- Test by placing a spoonful on a cold plate; it should set after a minute.
3. Fill the Jars
- Remove jars from hot water and set on a towel.
- Ladle hot jam into jars, leaving ~¼ inch headspace.
- Wipe rims clean, place lids on top, and screw on bands until fingertip-tight.
4. Process the Jars (Water Bath Canning)
- Place jars in a large pot of boiling water, ensuring they’re covered by at least 1 inch of water.
- Boil for 10 minutes (adjust for altitude if needed).
- Carefully remove jars and let cool 12–24 hours.
- Check seals: lids should not flex up and down when pressed.
Storage
- Store sealed jars in a cool, dark place for up to 1 year.
- Refrigerate after opening; use within 3–4 weeks.
💡 Tips for Perfect Berry Jam:
- Mix berries for a unique flavor—raspberry + strawberry works beautifully.
- For smoother jam, use a hand blender before boiling.
- Add a pinch of cinnamon or vanilla for extra flavor.
