When chestnuts are roasting on an open fire, and Mario’s Chestnut Apple Ciambella is baking in the oven, more than Jack Frost will be nipping at your nose (and plate). This traditional Italian ring cake would be a lovely breakfast on Christmas morning, or a simple snack to pair with a cup of coffee. Mario’s version combines dried currants, ground cloves, and grappa, and the drop of mascarpone puts this spice cake over the top.
