A visit to Rajesh Gandhi’s sprawling bungalow in Ahmedabad isn’t complete without ice cream. As he makes himself comfortable in the large, white leather sofa in his living room, the 55-year-old Gandhi urges you to have a second helping, and a helper rushes to bring you another bowl. Most Amdavadis love their sweets but in this household, the importance of the cold dessert can’t be understated: Gandhi is the managing director of the ₹340-crore Vadilal Industries, the ice cream business started by his great-grandfather.
