What each ingredient does

Hard-boiled eggs: Provide the main body of the sauce, thickening it with finely chopped egg texture.
Melted butter: Adds richness and a smooth, fatty mouthfeel to the sauce.
Milk: Loosens the chopped egg into a spoonable sauce and adds mild creaminess.
White stock: Adds savoury flavour and liquid to carry the egg and butter together.
