This pumpkin spice syrup is a coffee-shop style flavoring made from a plain sugar syrup simmered with real pumpkin puree, cinnamon, ginger, nutmeg and cloves, then finished with vanilla. It takes about 15 minutes on the stove and makes roughly 1 1/4 cups, enough for 10 to 20 drinks, so the flavor is available at any time of year.
The base is equal parts sugar and water, with a little brown sugar for a deeper, caramel-like note. A gentle simmer is all it needs: the sugar dissolves, the spices bloom and the pumpkin cooks into the syrup. Straining through a cloth-lined sieve removes most of the pumpkin fiber and spice sediment, which gives a smoother syrup that mixes cleanly into drinks.
Use 1/2 to 1 ounce (1 to 2 tablespoons) in a homemade pumpkin spice latte, or stir 2 to 3 teaspoons into a mug of drip coffee. Plain canned pumpkin works in the syrup, and so does homemade pumpkin puree.

Ingredients
Method
- Combine the water, granulated sugar and brown sugar in a small saucepan. Set over medium heat and stir until the sugar has dissolved and the liquid is clear, 2 to 3 minutes.
- Whisk in the pumpkin puree, cinnamon, ginger, nutmeg, cloves and salt until no lumps of pumpkin remain.
- Bring to a gentle simmer, then turn the heat down to low. Simmer for 8 to 10 minutes, whisking now and then, until the syrup has thickened slightly. Keep it below a hard boil so it does not reduce too far or scorch.
- Take the pan off the heat and stir in the vanilla extract. Let the syrup cool for about 10 minutes.
- Line a fine mesh strainer with a double layer of cheesecloth or a clean thin cotton cloth and set it over a bowl or measuring jug. Pour the syrup through and let it drip; stir gently with a spoon to help it along, but do not force the solids through.
- Pour the strained syrup into a clean glass jar or bottle, close it tightly and refrigerate. Shake before each use.
