I had the advantage of reading all your trials and tribulations, so I went straight for the Maseca. I also saw that it made 12 pupusas, so I cut the recipe in half.
But that only gave me 5, and small ones at that.
I have a problem when it comes to stuffing things...
I always overstuff. And this was no exception.
I'm thinking I'll roll the dough thinner next time.
I'll also add salt.
Overall this was great though! I've never had pupusas, so I don't know if mine turned out authentic, but they sure did turn out tasty!
