Even though Stef Ferrari founded Hay Rosie Craft Ice Cream Co. just this past year, she’s been a lifetime fan of the creamy dessert. Based in Brooklyn with her wife M.Dickson, Ferrari often travels to test new ingredients and create innovative flavors (like Sage Chocolate Chip and Brownie Brickle Crunch!), but always brings local snacks to remind her of home. Ferrari has a solid list of packing staples, including sunglasses made from recycled surfboards, a good book for unexpected delays, versatile shoes that can be dressed up or down, and most importantly, sweet memories of ice cream to share.
