In Japanese cooking, a makisu (巻き簾) is a small mat woven from bamboo and cotton string that is used in food preparation.
[1][2] Makisu are most commonly used to make a kind of rolled sushi called makizushi (巻き寿司), commonly called maki.
Some cooks cover the makisu with plastic film before use to reduce the cleaning effort.
This is especially necessary for producing uramaki (裏巻), a kind of maki with the rice on the outside of the roll.
[3] After use, a makisu should be scrubbed to remove food particles and thoroughly air dried to avoid the growth of bacteria and fungi.
