This special copper plate in the shape of an aubergine is a gem that cannot be missing among the tools of a good Japanese chef, but it also lends itself to useful functions in everyday cooking. It was created to perfect the preparation of the famous Japanese pickles, the tsukemono (漬物): just put it together with the pickles - in the rice bran paste used for their preparation - so that the action of the copper ions brings out the color and flavor of the pickled vegetables. But you can also simply take advantage of the bactericidal effect of copper, immersing it in water to obtain further purification of drinking water, also excellent for spraying plants. Copper 100%. A small, precious gem useful for the expert cook but also for everyday use. 4 cm x 8 cm x 0.2 cm
