The twigs of the Ho (Magnolia hypoleuea), of the oak, or of the Keyaki (Zelkoiva Keaki) are made up into faggots, which are placed upon the bottom of the sea, at low tide, and after 30 or 40 days the weeds grow around the faggots. After severing it from the faggots, it is thoroughly washed several times, in order to remove the dirt clinging to it, and then it is put into tubs and cleaned with pure water. After it is thoroughly cleansed, it is dipped out of the tub with a grain measure, spread on a raised stand, called nagashi dai, that has been previously covered with bamboo screens. To prevent the substance from running over each screen is surrounded with a rim. The weed is left until the water has all oozed away. The rim is then removed, and afterwards the screen with the porphyra vulgaris is taken off, and the latter is picked off and exposed to the rays of the sun, after which it is stored. Recently the modes of procuring and of preserving this sea-weed have been improved to some extent, there has also been an increase in the variety of ways of curing it, either in the green state or by drying and salting it (such are Ajitsuke-nori, Matsuba-nori, &c.). Use.—To prepare the cured weed for table, it is placed over a fire and dried, and then eaten with rice; it has a very delicious bouquet and flavour, and is highly esteemed by every one. Analysis.
