There's nothing new about the combination of sausage and eggs, but sometimes it's good to go with what works. In concept, scotch eggs are incredibly simple—an egg wrapped in sausage then breaded and deep-fried. But as with most truly great foods, the sum is more than its parts. Even those who are normally put off by a hard cooked egg find it hard to resist one wrapped in sausage.
Experimenting with how soft you can cook the egg before wrapping it in sausage is fun, and the failures are delicious. A three-minute egg is the coolest I've been able to handle. And although I've recommended bratwurst, use whatever is your personal favorite.
