When the dough has doubled take it out of the bowl and make balls of 70-75 grams (divide in 10, or 8 for really big conchas). Put the balls on abaking sheet covered with parchment paper.
With the paste make balls and press them into a circle to put on the top of the conchas. Using the back end of a knife, make the design on the conchas by pressing down through the covering and into the dough (but without cutting through the dough.)
Once you’ve formed the conchas cover with a towel and let sit for one more hour. You’ll see that while it rises more the shape will become more distinct.
Pre-heat the oven to 320 ºF and bake the pan dulce for 25 minutes. Once they’ve baked for 25 minutes take them out of the oven and let them sit on a cooling rack for 10 minutes.
