First, poking the sausages before cooking. Don’t do it! That’s where all the juicy goodness lives. Pricking them is for making sausage-shaped soup, not for frying. Second, using high heat right out of the gate for the boil. Start cold water for even cooking, remember?
Third, overcrowding the pan. If you pack a dozen sausages into a tiny skillet, they’ll steam instead of fry. You’ll end up with sad, gray, sweating sausages. Give them personal space. They deserve it. They’ve come a long way from being a tube of seasoned meat.
And finally, cutting into a sausage right after frying. Let it rest for two minutes! Let those juices settle. If you cut into it immediately, you’ll watch the flavor run out onto the cutting board, and you’ll feel a little hollow inside. We’ve all been there.
