Believe it or not the exotic green fruit in the above picture is the Laranja (aka the common Orange).
According to Wikipedia “Brazil is the largest orange-producing nation in the world, and production is located primarily in the state of São Paulo, which accounts for approximately 80% of Brazil's production and 53% of total global FCOJ (frozen concentrated orange juice) production (in the region of Campinas, São Carlos, São José do Rio Preto and Barretos, and the western part of the state of Minas Gerais)”
So if São Paulo is orange central are oranges actually supposed to be green? And if so why don’t we call them “greens” instead of “oranges”?
My theory, which is of course completely unsubstantiated, is that they export all the orange oranges and leave us city folk back home with all the green duds which they couldn’t sell. If anyone’s got a better theory let me know. In nay case they taste quite alright, so I’m not complaining…
