This easy blackberry jalapeño jam is sweet, spicy, and bright — made with simple ingredients and ready in 10 minutes. No additives or special equipment required — just fresh (or frozen) blackberries, a little honey, and one jalapeño for the perfect sweet-heat balance.

Ingredients

  • 12 oz blackberries (fresh or frozen)
  • 1 medium jalapeño pepper, finely chopped (or ¼ cup jarred diced jalapeños)
  • ¼ cup organic cane sugar
  • ¼ cup honey or pure maple syrup
  • ¼ cup water (use only 2 Tbsp if using frozen berries)
  • 1 tsp lemon juice
  • ½ tsp sea salt
  • 1 tsp chia seeds (Optional for natural thickening and fiber)

Instructions

  • Prep the pepper: For mild heat, remove ribs and seeds. For more spice, leave some in.
  • Combine: Add blackberries, jalapeño, sugar, honey, water, lemon juice, and salt to a small non-stick or ceramic saucepan.
  • Cook: Bring to a boil over medium-high heat, stirring often (about 2 minutes).
  • Simmer + Mash: Reduce heat to medium-low and simmer for 6–8 minutes, mashing berries with a fork or using an immersion blender.
  • Thicken + Cool: Remove from heat, stir in chia seeds if using, and let cool 10 minutes.
  • Store: Pour into clean glass jars and refrigerate up to 2 weeks.

Notes

  • Texture check: Jam is done when it coats the back of a spoon and the bubbles look syrupy.
  • Make it milder: Use half a jalapeño or jarred diced peppers for gentler heat.
  • Make it spicier: Keep some seeds or add a second pepper.
  • Flavor variations: Add a pinch of cinnamon or fresh ginger for warmth.
  • Serving ideas: Spread over goat cheese, use as a glaze for grilled chicken, or swirl into Greek yogurt.
