Preheat your oven to 375°F (or whatever the box says—they’re the experts). This is not the time to be a rebel. If the box says 375, you set it to 375. No negotiations.
While the oven heats up, you have a few minutes. You can do a little dance, check your phone, or just stare at the pie. I recommend the dance—it improves the pie’s flavor, scientifically.
