| Beginning
Agar agar is a natural gelling substance stemming through the faction walls of red algae, of the gelidiacees family, in the vein of gelidium and gracialaria. They've long been advantaged in numerous Asian cookery traditions. Moreover, the family name agar-agar is without a doubt of Malay-Indonesian beginning and means jelly. The Japanese legend tells that the unique manufacturing treat of the agar-agar was learned in the mid-seventeenth century. One wintery sunset, a Japanese officer would have always been offered a traditional dish of jelly created from gelidium seaweed boiled in standard water, by the owner of a little inn. Following the evening meal, the innkeeper would've fearful the remainder of jelly outdoors. Within a handful of days and after several cycles of freezing, thawing and drying in the sun, a white substance seems to have showed which the landlord will have assembled and boiled. He would have obtained a gelatin whiter than the original and whose texture in the mouth would have thrilled the Japanese ever since. The same procedure of freezing as well as thawing is still employed today, on a large scale, to extract and purify the agar-agar of the seaweed from which it originates.
Properties
Agar-agar is actually wasted for its gelling functionality and the unique properties from the gels obtained by it. Gelling occurs when a mixture of agar-agar has cooled in a liquid that was previously brought to a boil. Depending upon the species of algae used, gel formation will take place at temperatures between 32C and 43c (90F and 110F).
Your agar-agar gel will retain its suppleness even when subjected to temperatures grazing 85F, unlike gel-based gelatin, which melts at 37C (99F). This wide gap between the temperature at which your gel is formed and the temperature at which it melts is special.
Agar-agar does not impart flavor or smell to mixtures; it actually promotes the release of other aromas in the mouth. It is usually used in very low dosage, since gelling is evident at levels of concentration of agar-agar below 1%. The firmness of the gel is precisely proportional to the content level of agar-agar used inside a dish. The weaker the dosage of agar-agar, the more supple and fragile the gel is going to be; the stronger the serving, the more firm and brittle the gel will be.
Inventive cooking applications
Agar-agar is one of the flagship additives of molecular gastronomy. It really is used to make dishes using unusual shapes and textures for example pearls and spaghetti gels. Simply dissolve the powdered agar-agar in a boiling aqueous liquid, then allow it to set while cooling, making use of various techniques. It is also built-in into preparations using a food siphon to produce really light foams.
Agar-agar preparations are high temperature resistant, thereby making it potential to serve hot foams and gels. |
