Pomelo (Som-O)

Pomelo (Som-O) stands as the largest citrus fruit on this list, often weighing 1-2 kilograms with a thick pith protecting sweet-tart segments. Each serving provides 230% of the daily vitamin C requirement, making it 50% more potent than an orange in immune support. Compared to Longan's pure sugar rush, this fruit offers a complex, layered sweetness that lingers.
