At Sorveteria Rocha I, the most popular specialty scoop shop in São Sebastião, you can get a scoop of acai ice cream topped with sprinkles, marshmallows, and hot fudge, and take popsicles to go. The family-run place has been serving 61 flavors since it opened in 1947. Or visit Gelato Donato in Sao Paulo for their signature cheese and guave ice cream. You can even take your ice cream high-end at D.O.M., the home of Alex Atala, Brazil's most famous chef. There he serves a jabuticaba ice cream, made of a fruit that looks and tastes like grapes but with a citrisy twang, and is tinged with a sinus-clearing hit of wasabi.
