Ever had an Ugly Orange? Or 'Tangelo' (I think they're imperceptibly different but basically the same).
It's an orange-pomelo hybrid and it's objectively the greatest fruit on the planet. Objectively.
It's an orange with superior texture and flavour, a cushion of air inside that allows you to simply pop it open, and less sugar content than you cited for oranges. Keep an eye out!
Yeah, I've seen and eaten these back in the day, a friend had a tree. Not too bad and no peeling issues as you say!
