We're crushing hard for this citrus. Meet the unique mandarin with a distinct little man bun. Seedless, sweet, and easy to peel, they're also known as "Hallabong" in Korean. The Dekopon is a hybrid of Ponkan, Satsuma, and another sweet Japanese Trovita citrus, which adds up to insane sweetness. These prized "dekopons" that took years to perfect in Japan went for $10 a piece at one point. You're looking at solid gold here.
