Cooks Note: Drain the pumpkin purée on paper towels to reduce water and concentrate the flavor. The purée is then used in both the dough and filling in this recipe to elevate the pumpkin flavor and prevent the filling from becoming too dry. Apply the chai glaze when the knots are slightly warm so that it melts into all the nooks and crannies. This dish is best served warm. To reheat the knots in the oven, place them into a preheated 300°F oven for 10-15 minutes or in the microwave for a minute on the standard setting.
