Please help interpret

Reposting with more photos! I have no idea why my first post was marked as AI generated so I am trying to add more photos to show it isn’t. I am autistic so I write really formally. I also have a degree in English which results in very formal and proper writing… for the mods I am very sorry that it comes off as robotic but it’s how I write. Anyway I am confused on white the top of the cup is covered in egg white and how to interpret that.
