Kimchi is a millennia-old, preserved food of Korea, and kimjang, the making and sharing of kimchi to be eaten over winter months, was designated as a UNESCO Intangible Cultural Heritage of Humanity in 2013. Napa cabbages and Korean radishes are salted, coated in red pepper powder, garlic, and other savory ingredients, and then left to ferment. As each family developed their own recipe, kimchi became more diverse with each passing generation.
