Chocolate Cosmos by Kumud Dwivedi

(This recipe appeared in the Winter 2022 issue of Pastry Arts Magazine)

This recipe, a cake fashioned to look like an éclair, comes from the beautiful new book Dark Side of the Bean: 150 Sweet Temptations (Roli Books, 2021) by pastry chef Kumud Dwivedi. Born to a Punjabi family in India, Kumud describes herself as a “dessert-obsessed insomniac” who believes that desserts are “the perfect combination of science and creativity.” As a child, she spent her pocket money buying second-hand international food magazines on the street of Delhi. Though she was drawn to the food industry, Kumud took the advice of elders and embarked on a career in the corporate world, where she worked for a decade. When her son was born, she left her job and opened a small, exclusive patisserie in Kolkata. It was when her family moved to Bangalore that she decided to get serious and hone her pastry skills by taking classes at École Nationale Supérieure de la Patisserie in France, the ZDS in Germany and the Christophe Morel Academy in Canada. Kumud went on to intern with Alfons Wachter, a third-generation baker in Zams, near Innsbruck, Austria, as well as top pastry chefs in Europe, Thailand, UAE, Canada and the United States.

Dark Side of the Bean is a collection of 150 professional level dessert recipes that reflects Kumud’s training and expertise and serves as a tribute to the people she has worked with or learnt from, and the countless desserts she has enjoyed over the years. Available from amazon.com.

Here’s what Kumud has to say about this dessert:

“My inspiration for this dessert was the chocolate éclair, which I wanted to turn into a cake, using the classic combination of chocolate, orange and hazelnut. The elegant smoothness of Chocolate Diplomat cream with the freshness of Orange Confit and crunchiness of Caramelized Hazelnuts, along with the exposed layers, is what makes this cake unique and one of my all-time favorites.”
