What is Acorn Jelly Powder (Dotorimuk Garu) ?
Acorn (Dotori 도토리) is the fruit of the oak tree Quercus dentata which is a species that grow in Korea, Japan and China. In Korean, it's called 떡갈나무 Tteok-Gal-Namu. The acorns from this tree is used to make acorn jelly Dotorimuk (도토리묵) or acorn noodles or Dotoriguksu (도토리국수). It has been one of the local delicacies of mountainous regions.
Because acorns are quite bitter and astringent, the acorns need to be dried, soaked, ground, then rinsed several times and then the sediment is then collected and dried again to make powder. To see how you can make jelly from the powder, you can read How to make Dotorimuk post here.
