Here’s the simplest advice I can give: if you’re asking the question, it’s probably not done yet. Your gut instinct is usually right.
Pork sausage is one of those foods that loves to play tricks. It looks done, feels done, but lurks in the shadows of undercookedness.
So cook it until you’re annoyed. Then wait two more minutes. Take it off the heat, let it rest for a minute (don’t skip this!), and then dig in. You’ll be rewarded with a snap, a sizzle, and a peace of mind that no raw center can touch.
And hey, if you still mess up? That’s why pizza was invented. You’ve got this.
