Wooden plates we can buy from most Japan Surplus shops are very useful in our kitchen. They of course can be used as the regular purpose – do not be afraid of the varnish you see, for eating purposes the manufacturers of course used a health-friendly, we call that food-grade varnish. No harm when small chips ingested. I believe that is true because I knew of dyes that come from natural source like plants and the dye for chorizo from a kind of bug as seen in Food CIA. Government agencies regulating manufacturing plants will not allow harmful products be made like the function of Health Departments.
Aside from being used a dish or plate. I found a more useful function for wooden plates.
No more stains on your table, no broken tiles, no more burned table cloth! Yes it can be used as a pot rest instead of thin holders made of cloth or rusting and rocking metal tri-pods why not a solid wooden plate to replace them?
It is a good pick because most are made-up of thick wood, some are bowl high – this can avoid heat from reaching the surface of the table. And mind you, it looks good on the table, better than the conventional pot rests J Buy yours now, it will not cost you a lot. I bought mine for about half a dollar each. Is it not amazing?!
