Divide the crumbled bacon or sausage (if using) between the silicone egg bite molds. In a medium mixing bowl, whisk together the eggs, shredded cheese, cottage cheese, cream, and salt. (Alternatively, you can blend these ingredients in a blender.)
Divide the egg mixture between the molds. Cover the molds with aluminum foil.
Pour the water into the inner cooking pot and place a trivet in the bottom. Place the molds on top of the trivet. Lock the lid, select Steam, and set the time to 8 minutes. When cooking ends, let the pressure release naturally for 10 minutes, then turn the valve to “venting” to quick release the remaining pressure.
Unlock and remove the lid. Remove the silicone molds from the pot. Allow the eggs to rest in the mold for 2 minutes before removing.
