It requires "Dates". I was wondering if those are accessible, or should be at least, at your nearest grocer.
Since this is the vegancooking site, I will give out the whole recipe::
3 small dates
1/2 cup soy milk
1/2 cup plain canned pumpkin (or more)
cinnamon, nutmeg, ginger (or pumpkin pie spice)
splash vanilla extract
ice cubes (maybe 1 cup)
If you're planning ahead of time, soak the dates in the soymilk overnight. Other than that, toss everything into the blender and blend it up! Change the quantities of items to match your thickness/pumpkinness preference.
