What each ingredient does

Hard boiled eggs: Yolks provide richness and a smooth, binding base for the dough.
Soft butter: Adds fat and moisture, helping the yolk mixture blend smoothly and stay tender.
Flour: Gives the mixture enough structure to hold together as a dough that keeps its shape in liquid.
