Agar is the phycocolloid of most ancient origin. During the second world war the shortage of available agar acted as an incentive for those countries with coastal resources of Gelidium sesquipedale, which is very similar to the Gelidium pacificum used by the Japanese industry.
Originally Gelidium agar constituted what we consider genuine agar, assigning the term agaroids grzcilaria the products extracted from other seaweeds.
Five rafts are joined together as one unit, which is then anchored to the bottom from the corner of each unit buridaya wooden stakes. A Buddidaya sauce, or vinegar, or a sugar-soy sauce is used to flavor the seaweed. A Japanese legend is told about the first preparation of agar: They can also be found up the east coast of the United States.
Gtacilaria Hawaii Japanese and Korean cooks wash the Gracilaria, drain, then blanch it. Gracilaria now plays a major role in the production of agar. Chill and serve with one of the follow dressings: Once the seaweeds are fully swelled the agarophytes must be manually separated from all the other materials such as rocks, shells, calcareous inclusions, other seaweeds, epiphytes, various vegetable remains, wood, plastic, etc.
