| Starting point
Agar agar is actually a ordinary gelling substance stemming from the cell walls of ruby algae, of the gelidiacees category, like gelidium and gracialaria. They've long been handled in many Asian cookery traditions. Moreover, the name agar-agar is without a doubt of Malay-Indonesian beginning and translates as jelly. A Japanese legend tells that the innovative manufacturing process of the agar-agar was found in the mid-seventeenth century. One winter sunset, a Japanese officer would have actually been offered a customary dish of jelly concocted right from gelidium seaweed boiled in water, by the holder of a small inn. Subsequent to dinner, the innkeeper would've thrown the vestige of jelly outdoors. Within a handful of days and after many cycles of freezing, thawing and additionally drying in the sunshine, a white substance seems to have come into sighted which the landlord would have collected and boiled. He would have attained a gelatin whiter than the first and whose texture in the mouth would have delighted the Japanese ever since. The same procedure of freezing in addition to thawing is still used today, on a large scale, to draw out and purify the agar-agar in the seaweed from which it originates.
Properties
Agar-agar can be used for its gelling capabilities and the exceptional properties of the gels geted by it. Gelling occurs when a mix of agar-agar has cooled in a liquid that was prior to this brought to a boil. Depending entirely on 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 temps grazing 85F, as opposed to gel-based gelatin, which melts at 37C (99F). This wide gap between the temperature at which a gel is formed as well as the temperature at which it melts is special.
Agar-agar does not impart flavor or scent 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 actual firmness of the gel is directly proportional to the strength of agar-agar used in a dish. The weaker the dosage of agar-agar, the more supple and fragile the gel will be; the stronger the dose, the more firm and even brittle the gel will be.
Inventive cooking applications
Agar-agar is amongst the flagship components of molecular gastronomy. It really is used to make dishes with unusual shapes and textures like pearls and spaghetti gels. Merely dissolve the powdered agar-agar inside a boiling aqueous liquid, then let it set while cooling, using various techniques. It is also built-in into preparations using a food siphon to produce very light foams.
Agar-agar preparations are high temperature resistant, thereby making it possible to serve hot foams and gels. |
