I enjoyed the article. Thanks for posting the link, Mike.
I am a bit puzzled by the author's claim that oats require more salt. She gives the example of morning oatmeal, but I never add salt to my steel-cut oats. There is some sodium in the 1/4 cup of milk that I add.
I baked oat bars yesterday, and as I did, I realized the recipe does not have salt, but that is likely because I replaced the margarine with unsalted butter. However, the recipe does contain coconut, which would have sodium, as well as orange marmalade.
Certainly I know that my shortbread and my sugar cookies are better with at least 1/4 tsp. salt per stick of unsalted butter, and sometimes a bit more. I once made a recipe without realizing that it should use salted butter, and those cookies were not worth the eating.
So, when should we reduce salt, and when should we not?
