I had some free time today so I decided to try this recipe. I made chocolate shells. I followed the recipe and subbed out 10g of almond flour with cocoa powder. I have a gas oven and leaving the oven door slightly open for 5 mins, I started smelling the gas from the oven so the second batch I air dried it.
