We put our winter citrus marmalade to work as the feature of our thumbprint doughnuts. The aromatic, sweet, sour, bitter and spicy marmalade compliments the yeasty fragrant vanilla doughnut cluster. The marmalade nestles into a slight indentation I put in the center of the cluster. Marmalade is often thought of as a tough sell. But there is a distinct and loyal audience who need marmalade and an even greater group who can need to be introduced to it. The doughnut is the ideal ice breaker.
