This dessert is modeled after the famous Mont-Blanc Aux Marrons, a masterpiece formed of pureed, sweetened chestnuts covering whipped cream to resemble the snow-capped mountains. It is a bit labour-intensive because the chestnuts are braised for hours before they are mashed, but consider that our version calls for a soft sponge base topped with fresh cream and covered with a luxurious mound of merlot infused chestnut swirl. It is an absolute pure indulgence that will be worth your efforts.
