Combine the base. In a medium saucepan, add pumpkin puree, apple cider, brown sugar, and maple syrup.
Stir until smooth.
Add the spices. Sprinkle in cinnamon, ginger, nutmeg, cloves, and a pinch of salt. Stir to blend evenly.
Simmer low and slow. Set the heat to low. Cook uncovered for 20–30 minutes, stirring every few minutes so it doesn’t splatter or scorch.
You want gentle bubbles, not a rolling boil.
Check thickness. When a spoon dragged across the bottom leaves a brief trail and the mixture mounds softly, it’s ready. It will thicken more as it cools.
Finish with flavor. Remove from heat. Stir in vanilla and lemon juice.
Taste and adjust sweetness or spices if needed.
Cool and store. Let it cool to room temperature. Transfer to a clean jar and refrigerate.
