A good cutting board is made of Beech or white oak. Those woods contain natural tannins that fight bacteria.....and some hot water and soap gets the rest.
They should be wiped down with mineral oil, not vegetable, oil about once a month.
You're pretty fussy there, John, sir.
This is something I'd expect from the adroit sparkling old dude on Skins's island, as he's been a professional chef. But we laymen, no.
In fact, I'm imagining this scene right now, the adroit sparkling old dude getting ready to slice a cucumber.
He probably goes through a collection of cutting-boards made of various differing materials--wood, plastic, fiberglass, whatnot--and finally selecting the one appropriate for cucumbers, first carefully wipes it down.
Then the adroit sparkling old dude probably goes through the kitchen drawers to select the proper knife for slicing a cucumber--a big one, a small one, one with a serrated blade, one with a plain blade, whatnot--and finally selecting the one appropriate for cucumbers, first carefully hones the blade.
And then he proceeds to slice the cucumber, stopping after each cut to wipe off the blade with a towel.
Notice, please, I'm
not criticizing the adroit sparkling old dude, who knows what he's doing and how to do it. If such perfection rocks his chair, rows his boat, pushes his buttons, more power to him.
But me? Well, franksolich has been known for using a small hacksaw to slice cucumbers.....on the bottom side of a china platter.
Nothing bad happened; it's simply the difference between wanting to do something the "right" way, and just wanting to slice the damned things.
