So I followed the recipe by @Crystal Arvelo to a t besides adding cocoa powder. My shells came out a little flatter and still were a little hollow so not sure what I did wrong. I didn’t notice that my batter was a little more runny but not to bad. I think I hit a snag when it came down to adding the sugar to the egg whites. When I did the sugar and the water mixture was confident that I did it right I’m not sure if it was supposed to be full dissolved cause when it reached 118 degrees it wasn’t boiling for me. I also used bottle water am I supposed to use tap water? They are a little hard so I know I either need to cook them less or turn down the temp.
