In Japanese cuisine, a sushi oke (寿司桶), also known as a hangiri, is a round, flat-bottomed wooden tub or barrel used in the final steps of preparing rice for sushi.[1] Traditional hangiri are made from cypress[citation needed] wood bound with two copper bands. They range in diameter from about 30 cm (12 in) for use at home, to 1 m (3 ft 3 in) for use in a restaurant.
A shamoji wooden paddle is used with a hangiri to dress and to cool the rice. After cooking, the rice is transferred to the hangiri where it is tossed with a dressing made of rice vinegar, sugar, and salt. When the mixing is complete, it is covered with a cloth and allowed to cool.
A typical hangiri may cost two or three times as much as an expensive steel cooking pot.[citation needed]
Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
