This sweet-waxy corn is grown in black soil in China’s 47° north growing region, irrigated with Nenjiang River water and harvested once a year. Whole cobs have plump, glossy purple-black kernels that naturally contain anthocyanins.

When cooked, the kernels become soft and slightly translucent, with sweetness and a springy, chewy texture. Serve as a snack or alongside other grains at family meals.
