Here in the states we’d call this limeade. I made this tonight, and it was very good. I used sweetened condensed coconut milk (dairy allergy) and ended up doubling the amount because it was too tart for me with the amount given in the recipe. Your mileage may vary.
Hope the website helps you to feel less homesick! Any Brazilian dishes you would recommend to someone who isn’t familiar with the cuisine?
Feijoada, feijão tropeiro, pão de queijo and acarajé
