There is one problem with my dough. After my pizza comes out of the oven it tastes great, good flavor, great bread texture. But let the pizza sit for 30 min, or send it on a longer delivery and the crust on the bottom of the pizza becomes tough. What could be the cause to this, and is there any way to make a pizza more delivery friendly? We use hot bags of course on delivery’s and the pizza always arrives fresh. its just tougher than a few minutes out of the oven. Thanks for any input.
