Hanji is traditional Korean paper made by hand one sheet at a time. Artisans turn the weblike fibers of paper mulberry trees into paper that can last more than a thousand years. The most expensive hanji costs over $20 per sheet. But despite hanji's quality, demand is in decline.

• A 1-kilogram bottle of artisanal rice syrup can reach $140.

• Sikhye takes days — and nights — of hard work to achieve.

Rice syrup is a staple in Korean cuisine.
