The story the reviews tell

Dotoriguksu arrives as a bowl of quiet specificity—noodles made from acorn flour that shift in flavor depending on which oak species gave up their crop. Red oak or white oak each leave their own mark on the broth. The noodles themselves are a blend: acorn starch bound with buckwheat or wheat flour, salt holding it all together. Because oak hybridization makes exact species identification nearly impossible, the soup's exact character remains somewhat opaque—a dish that tastes of a particular tree, even if no label will tell you which one.

What makes this version distinct

Acorn noodle soup, also called dotoriguksu (Korean: 도토리국수; lit. 'acorn noodle'), is a noodle soup consisting of Korean noodles made from acorn flour or starch, salt, and a combination of grain-based flour (usually buckwheat or wheat). Acorn noodle soup may be made from acorns collected from red or white oak species and each oak species gives a distinct flavour. Ingredient labels do not list from which type of tree acorns are gathered, most likely owing to the large number of oak species and increasing oak hybridization (especially among white oak varieties), which makes it difficult to recognise and document each type of species.
