I answered myself, "Because these tools have stood the test of time, and done the job well. Most of them for at least 10 years."
Then I pondered..."Why not post a series about these tools? Maybe others would like this info."
So without further ado, (I like that phrase ;0) here is the first entry.
1. Pizza Stone, I have 3 of these. They start out as a light tan, rough surfaced disk. But after many, many uses they become dark and slick. Care for them as you would a cast iron skillet. I bake everything I can on them.
2. The Original Dish Drying Mat, very absorbant, washes up well. I have 2 and will probably get at least 2 more. They are a nice size, I use 1 as a doggy placemat and possibly will get 4 for informal place mats for the table.
