I just wanted to make sure you know that food poisoning happens even when all microorganisms are already dead. Some bacterial toxins are resistant to high temperatures and can still cause disease even after their source has been killed. That’s why cooking something that’s been sitting around in warm or room temperature doesn’t make it safe to eat, even though it makes of safer than not cooking it.

I thought so as well. Maybe the other side of the protruding sausages were progressively squeezed out by the dough starting from the tip, and it’s probably due to the proximity to other rolls in the back, or maybe the center of the oven was much hotter and ended up cooking (and growing) the dough unevenly. That explains why the tip of the sausages looks popped.

True. I live in Brazil and I run my car exclusively on ethanol. It’s a biofuel made from sugar cane and thus is renewable and has a low carbon footprint.
