As for your question re the sour cream pastry. I think the symbol just means the actual bowl in this recipe. I believe it is Tenina's recipe but the recipe is not clear. You would have to have it in the closed lid position and press turbo to make fine breadcrums as stated. Do it a few times. Hope that helps.
