Pour soy milk into sauce pan. Add egg and yolk, sugar, pumpkin pie spice, cinnamon salt & vanilla. Turn stove on med-high and whisk well.
Continue to whisk regularly, just before the mixture would come to a boil you will notice it thicken and the froth at the top will start to hold it's form better. At this point remove the pan from burner and quickly whisk in pumpkin.
Pour into serving mugs and grate nutmeg over the top
Notes
If you prefer an alcoholic beverage, include a shot of rum or whiskey when you add the pumpkin.
