What each ingredient does

Hard-boiled egg yolks
Mashed, they form the soft, rich body of the balls.
Raw egg yolks
They bind the mixture and set when heated, holding the balls together.
Flour
It absorbs moisture and helps the mixture keep its shape.

The step that matters

Drop the balls into boiling water.. The raw yolk only sets when it is hot enough, so the water must be at a full boil. In cooler water the balls can fall apart or cook unevenly, because the proteins need heat to coagulate and hold the ball together.
