Ladies and gentlemen, burger lovers of all shapes and sizes, I present to you The Cheeseburger Eggsplosion. 

It may not look like much, but this burger houses a secret. It's an all-beef burger patty with an egg cooked right into the center, seared in a cast iron pan until golden brown and crisp, topped with American cheese, and served on a soft, toasted potato bun.  When all goes right, the egg whites gets cooked through, but the yolk stays beautifully soft like liquid gold. Once cooked, it looks just like a regular burger from the outside, And the very best part? After cutting out the circular section for the egg (I used a small cup to do it), you end up with two slider-sized burger patties.  Click here to see this how to make this miracle.  http://aht.seriouseats.com/archives/2011/04/the-cheeseburger-eggsplosion-a-burger-with-a-fried-egg-center.html
