I came up with this recipe based on another recipe I found in an old cookbook. They are really delicious. The strong toasted oat/vanilla taste combination is a real winner in my book. The salt is there to bring out the flavor. It doesn't make the cookies salty, but if you leave it out, the cookies taste flat and rather dull. A good quality vanilla is essential to this recipe. Toasting the oatmeal is a very important step. It makes the oat flavor stand out and gives them a nice texture. You need to use the old fashioned rolled oats, not the quick-cooking kind. These cookies are very flat and chewy with a crisp (lacy) edge. The edge stays crisp even after storing them for a couple days.
