You want enough dough on the edge to make a nice handle. One that you can crack open and scoop out the soft doughy goodness from if you want.
If a big bubble develops in this outer edge, even better.
When i make homemade pizza i like to use frozen bread dough as the crust.
I just recently used frozen bread dough to make pizza - sometimes we use hoagie rolls split in half...so far I haven’t found any stores here that sell fresh pizza dough. Sams sells theirs by the case but I don’t want a case of frozen pizza dough. I have a bread maker that can make dough but I’m always trying something different.
