Notes
To make vegan pumpkin-spiced butter, you can replace dairy butter with any plant-based butter.You can also replace honey with maple syrup.If your pumpkin puree has too much liquid, cook the purée, frequently stirring, for 15 to 18 minutes or until smooth and thickened. We’re looking to cook down most of the water in the purée, so you can take it off the heat whenever the simmering purée stops producing visible steam.
