Our newest field correspondent, Papa J, send this to me. As he said "3 'identical' boxes of cheap Totino's pizzas I was recently preparing." Click the picture to enbiggen.
Soooo, anywhere from 11 - 16 minutes. That's a mere 45% variance in time. All at 450°. Nothing could possibly go wrong with that. And I love the fact that all three have different times. Maybe what happened is that the box maker messed up. Of course sometimes the box can be confused for a Totino's pizza...
