Aiyu jelly, known in Amoy Hokkien as ogio, and as ice jelly in Singapore, is a jelly made from the gel from the seeds of the awkeotsang creeping fig found in Taiwan and East Asian countries of the same climates and latitudes. The jelly is not commonly made or found outside of Taiwan, Malaysia, and Singapore, though it can be bought fresh in specialty stores in Japan and canned in Chinatowns. It is also used in Taiwanese cuisine.
In Cantonese cuisine, it is also known as man tau long (文頭郎). It is commonly served with a slice of lime.
