If you happen to wander into a cafe in Japan called Orto Cafe, you happen to eat there from dishes that … are also edible.
Japanese designer Nobuhiko Arikawa came up with this set, which looks like grandma's pancakes, to replace paper disposable tableware - after all, it is not very pleasant, anyway, and ordinary reusable tableware is impractical. From contact of food with food, a person does not experience unpleasant emotions, and such dishes are made very simply.
Of course, these are not pancakes. These are biscuits - baked goods made from a very simple dough consisting of flour, salt and water. Traditional ration for sailors on long voyages: after all, they are well stored, they simply have nowhere to stale. The biscuits are very dry and will not affect the taste of the food in any way.
So if they are not wet, these plates will be stored for months without becoming moldy or deteriorating in any way. Convenient, unusual and practical.
And especially hungry consumers may not throw away their dishes, but gnaw them. Or feeding a biscuit smelling of rice and meat to dogs or birds is also a matter.
