Add the pumpkin, honey, vanilla, pumpkin pie spice
, and salt to the saucepan with the coconut cream. Cook on medium heat until the mixture simmers. Reduce heat to low and simmer for 5 minutes, stirring occasionally. Remove from heat and pour into a large bowl that has been placed inside an ice-water bath (another bowl with ice and water). Stir the mixture to cool it faster. Let the bowl of pumpkin sit in the ice-water bath while you work on the next step. It's important to keep everything cold so the pumpkin mousse is stiff instead of soupy.
