I have a recipe that calls for ground chorizo, but I don't own a meat grinder and my local grocery store only sells chorizo sausages. Now, I guess I could mince the sausages and maybe achieve the same effect, but my question is, if I remove the casing from the sausage, will the insides essentially be ground chorizo?  edit: here's the recipe, http://www.johnsonville.com/recipe/chorizo-mac-skillet.html, it specifically calls for Johnsonville brand ground chorizo, so I'm unsure if it's Mexican or Spanish chorizo. That brand unfortunately isn't sold at my grocery store. 
I haven't made them but Stella Parks (BraveTart) claims that her cookies are "bonkers chocolatey". She tweeted, in response to your question:     My homemade Oreos are bonkers chocolatey due to the high fat Dutch cocoa involved; if they didn’t turn it that way, I’d blame crappy cocoa.   It's unclear whether you made the recipe or not but I think you should try it. Having more chocolate doesn't necessarily mean that it will taste more chocolatey. High quality chocolate used the right way will make a stronger flavor than more, low-quality chocolate.  She also pointed out that the percentages of the two recipes are very different.     The bakers % of those 2 recipes are v diff, so OP isn’t looking at the whole picture.   And she's right. I'm not an expert in interpreting baking percentages but there's a lot of difference between the two. Stella's recipe is more of a cracker/biscuit (UK). There's no egg in the recipe, not much moisture at all, so there's not much to spread. As such, the cookies are rolled and cut out and retain their stamped designs.   The other recipe is more like a cake (and the images support that interpretation); liquid egg, liquid chocolate... melted butter. They're rolled into a tube and sliced. This leads to a leavened, puffy cookie that spreads, ruining any design.  There may be a way to adjust the Flour Bakery recipe but I think you might find it simpler to start by trying BraveTart's recipe (using a good quality cocoa powder) and seeing what you think.
