Ingredients:

  • 2 cups (480 g) pumpkin puree (canned 100% pumpkin or homemade strained puree)
  • 1 cup (200 g) packed light brown sugar (or 3/4 cup / 150 g for slightly less sweet)
  • 1/2 cup (120 ml) apple cider (or unsweetened apple juice)
  • 2 tablespoons (30 ml) pure maple syrup or honey (optional)
  • 1 tablespoon (15 ml) fresh lemon juice (or 1 tsp white vinegar)
  • 1 teaspoon (5 ml) pure vanilla extract
  • 1 teaspoon (2.6 g) ground cinnamon
  • 1/2 teaspoon (1.1 g) ground ginger
  • 1/4 teaspoon (0.6 g) ground cloves
  • 1/4 teaspoon (0.6 g) ground nutmeg
  • 1/2 teaspoon (3 g) fine sea salt
  • 2 tablespoons (28 g) unsalted butter (optional; use coconut oil for vegan)

Instructions:

  1. Assemble and measure ingredients so everything is ready before you start.
  2. Combine base ingredients: in a medium to large heavy-bottomed saucepan, whisk together pumpkin puree, brown sugar, and apple cider until smooth.
  3. Add flavorings: stir in maple syrup (if using), lemon juice, vanilla, cinnamon, ginger, cloves, nutmeg, and salt until evenly blended.
  4. Bring to a simmer: place over medium heat and stir constantly until mixture just begins to bubble gently around the edges.
  5. Reduce and cook low & slow: lower heat to a gentle simmer and cook, stirring frequently (every 2–3 minutes) until mixture thickens and darkens to a glossy, jam-like consistency — about 30–45 minutes on the stovetop (or 2–4 hours on low in a slow cooker). Key cues: reduce roughly 30–40%, mixture will pull away from the pan when stirred, and a spoon dragged across the surface should leave a visible trail. Optional: blitz briefly with an immersion blender after thickening for an ultra-smooth texture.
  6. Finish and enrich: remove from heat, stir in butter or coconut oil if using, and taste; adjust salt, spices, or sweetener as needed.
  7. Cool and jar: let cool slightly (10–15 minutes), then spoon into sterilized jars leaving 1/4-inch headspace. Seal and refrigerate. Note: refrigeration will thicken the butter further; jars should be warm to the touch when filled.
  8. Optional long-term preservation: if you plan to make shelf-stable jars, process in a water bath canner following safe home-canning guidelines (acidification and processing times vary; consult USDA or trusted canning resources).
