Ganmodoki(がんもどき, 雁擬き?) is a fried tofufritter made with vegetables, egg white and sesame seeds. Ganmodoki means pseudo-goose (gan (がん, 雁?) + pseudo (もどき?)). This is because ganmodoki is said to taste like goose; compare mock turtle soup. Ganmodoki is also called ganmo for short. 
In the Edo period, ganmodoki was a stir-fried konjac dish. A dish similar to the ganmodoki today was made by wrapping chopped up vegetables in tofu (much like a manjū) and deep frying it.
