Add the pumpkin puree to a strainer lined with paper towels or a cheese cloth. Squeeze out as much liquid as you can out of the pumpkin puree. It should be more like a thick paste when you're done.
Add the strained pumpkin puree and all the remaining ingredients to a food processor and blend until smooth. It will likely take a minute or so of blending to get everything smooth.
Transfer the dip to a bowl. If you are not serving right away, cover the bowl with plastic wrap and transfer to the fridge. Remove from the fridge just before serving. Enjoy!
