I have a question about the recipe "Homemade Potato Chips" from Lara. What is the white powdery substance shown on the cooked potato chips in the Yahoo! pictures (2), but not in the picture shown on your website? In the text of your recipe, you mention buttermilk powder, and sea salt. I know it can't be the granular sea salt, but then why would you be throwing on spoonfuls of the buttermilk concoction after they are cooked? Thank you.
