If you enjoy McDonald's breakfast sandwiches, this may be life-changing information: You can get a real egg—not that rubbery mystery egg-like substance—on any breakfast sandwich (including the biscuit ones) just by asking for it.
J. Kenji Lopez-Alt shares this "secret" on fantastic food site Serious Eats:
All you've got to do is tell the cashier that you'd like your sandwich made with a "round egg" and they'll replace your folded egg patty with a real egg, free of charge.
The round egg is the one they put in their Egg McMuffin, made with a ring mold and, yes, a real egg. Of course, you can make many McDonald's foods at home, but now when you're out and about you can get a real egg sandwich made for you there.
