Mix flour, sugar, ginger, cinnamon, allspice and nutmeg together in a large bowl with a wire whisk. Cut in the shortening until mixture is like coarse crumbs.
Add buttermilk and pumpkin and mix with spoon. Turn onto a floured surface. I just pat these out with my hands and cut out. I used a juice glass because I wanted a smaller biscuit for these.
Bake in preheated 450 degree oven for 12 to 15 minutes. This made about 20 biscuits using a smaller cutter.
Notes
We love to serve these with butter, honey or molasses.
