Today’s batch was not bad, shells were a tiny bit hollow on some not all. Not real chewy like I’d been having. And they were not flat. This time I baked at 305 for 17 minutes. I left on counter 5 minutes to form a skin. Then popped in the oven. I followed Crystals instructions thru the meringue using the mixer, after that I folded the flour powder sugar in 1/2 then 1/2 I folded and checked to see how it flowed off the spatula, once like sap or a ribbon I put in piping bag.
