Dietary Attributes

- No pectin or preservatives
- Can be adjusted for less sugar if preferred
Ingredients & Substitutions
Ingredient List
- 2 ½ cups fresh blackberries (rinsed and dried)
- 1 ¼ cups granulated white sugar
- 2 jalapeños, seeded and chopped
- 1 tbsp freshly squeezed lemon juice
Notes on Quality
- Use fresh, ripe blackberries for the best flavor. Frozen blackberries can work, but thaw and drain excess liquid first.
- Choose fresh jalapeños that are firm and bright green for optimal spice.
- Fresh lemon juice is essential—it helps balance the sweetness and provides natural pectin to thicken the jam.
Possible Substitutions
- Swap honey or maple syrup for sugar to make it refined sugar-free (note: this may slightly affect texture).
- Use serrano peppers for extra heat or bell peppers for a milder taste.
- If blackberries aren’t available, try raspberries or blueberries instead.
Step-by-Step Instructions
- Prepare your jars – Make sure your jars, lids, and bands are clean and dry before starting.
- Combine ingredients – In a stainless steel pot, mix the blackberries, sugar, chopped jalapeños, and lemon juice over medium heat.
- Mash the berries – Use a spoon or potato masher to gently crush the berries as they cook, helping to release their juices.
- Cook until thickened – Stir frequently, allowing the jam to reach 220°F (the jam-setting point). This takes about 20 minutes.
- Check consistency – To test, place a small spoonful of jam on a cold plate and tilt it slightly. If it thickens and doesn’t run, it’s ready.
- Jar the jam – Carefully remove from heat and pour into jars, leaving ¼-inch space at the top.

- Seal and store – Secure the lids, let the jars cool, and store them in the refrigerator for up to 3 weeks.
Expert Tips & Tricks
Best Practices
- Use a deep pot to avoid boiling over when the jam froths up.
- Stir constantly to prevent sticking or burning.
- If you want a chunkier jam, mash the berries lightly. For a smoother consistency, blend slightly before cooking.
Common Mistakes
- Not cooking long enough – If the jam is too thin, it hasn’t reached 220°F. Keep cooking and testing.
- Overcooking – This can make the jam too thick and sticky. Remove it from heat as soon as it sets.
- Forgetting to seed the jalapeños – This can make the jam too spicy. Unless you want extra heat, remove the seeds before chopping.
Time-Saving Tips
- Prep all ingredients before starting to make cooking seamless.
- Use a candy thermometer to easily check when the jam is ready.
- Make a double batch and freeze some for later.

Pairings
- Spread on warm biscuits, scones, or toast
- Swirl into yogurt or oatmeal for a fruity twist
