Buldak Carbonara — social media "hacks"

The "Carbonara" flavor has been going around on social media with lots of 'hacks'. One combination I like is this one:

• Prepare exactly as the instructions on the package say.
  • Retain ½ cup of pasta water, and add it back to the noodles.
• Add ½ cup milk.
• (some people wait to add the built-in flavor packets until this point)
• Add ¼ cup shredded cheese (such as mozzarella).
• Add frozen corn and/or peas.
• Heat to a simmer and reduce the sauce some.
• Top with a little more shredded cheese.
• Top with furikake.

Other options

• add Japanese mayo
• mix in an egg yolk
• add in a poached egg
