I found this pumpkin ginger waffle recipe that I'll have to try sometime. Here's the recipe:
2 large eggs
3/4 cup buttermilk
1/2 cup canned pumpkin puree
1/2 cup sugar
3/4 tsp vanilla extract
3 tbsp melted and slightly cooled unsalted butter
How to make them:
1. Mix flour, baking soda, baking powder, salt, ground ginger and cinnamon in a large bowl. Toss 2 tbsp of this mixture with the crystallized ginger and set aside.
2. Whisk eggs, pumpkin, buttermilk, sugar and vanilla, and mix with flour mixture. Add butter, and fold in the crystallized ginger.
3. Heat the waffle iron, and use 1/2 cup batter for each waffle.
