Thank you for that. It’s always nice to be “corrected” by a stranger who has no idea what they’re talking about.

Having had both mandarin and orange trees in back gardens in Brazil, I stand by my confidence.

From a link posted elsewhere in this thread:

When they’re expose to temperatures below 55°F (12.7°C) for long enough, the green chlorophyll breaks down and the orange carotenoids surfaces in a process called “degreening.”

Are you confidently suggesting that in Brazil it doesn’t get colder than 12.7°C? I have a land plot on the moon to sell you. Or, if you prefer to be educated instead, I can point you to some lovely mountainous places to visit in Brazil with a chance to see snow and some of the absolute best artisanal chocolate in the world!

Hell when I was a kid I saw snow at ocean level even!
