Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Hard boiled eggs
Their mashed yolks form the bulk of the paste and give the balls a rich, tender body.
Raw eggs
They bind the mixture so the balls hold their shape when cooked.
Melted butter
Fat adds richness and keeps the paste moist and smooth.
Flour
Starch absorbs moisture and gives the mixture enough structure to hold together.

The step that matters

Gradually add flour until the mixture holds together. Adding too much flour at once or too much overall makes the balls dense and tough, while too little leaves them fragile and likely to break apart in the soup. Adding it slowly lets you stop when the dough just holds.
