Heat the oven to 300°F (150°C). Set a silicone egg bite mold or a well-greased 12-cup muffin tin inside a larger baking pan. Boil a kettle of water.
Blend the eggs, cottage cheese, Gruyère, cornstarch, salt, pepper and hot sauce for 20 to 30 seconds, until completely smooth. Let it sit 1 minute so the foam settles.
Pour the egg mixture into the 12 cups, filling each about three-quarters full, then sprinkle the crumbled bacon on top.
Carefully pour hot water into the outer pan until it comes about 1 inch up the sides of the mold or tin.
Bake 25 to 30 minutes, until the centers are just set with a very slight wobble, or 160°F on an instant-read thermometer.
Lift the mold out of the water bath and cool 5 minutes, then pop the bites out. Serve warm.
