Fill a pot with water. Then add some salt (few pinches) and vinegar (drizzle). Bring the water up to a boil. Once it is boiling, use a soup ladle to carefully place in 4 eggs. Set a timer for 11 minutes.
Drain the pot and place eggs in ice water. Or place under cold running water.
Peel eggs. Then use a knife to carefully separate egg yolk from white.
Carefully grate the egg yolk through a sieve. Use a spoon if you need to grate the leftover pieces.
Then use a knife to roughly dice the egg whites into smaller chunks
