Having encounter this dish several time, it always left me wondering, how can one boil cracked egg, maintaining the egg white in one piece. And my wife, on her quest to someday cook egg benedict, showed me the poached egg over the last weekend.
It is vinegar who does the trick. And she does another trick to make it perfect. Put dash of salt and pepper, and it was a good breakfast for the weekend. The egg white then goes with the toast.
Well done, you're one step closer to your egg benedict :D
