Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Egg Balls Fob Soup
Ingredients
Directions
Prepare the dough
Mash the yolks of the hard boiled eggs into a smooth paste with melted butter, pepper, and salt.
Add the raw eggs and mix well.
Gradually add flour until the mixture holds together.
Form the mixture into balls using floured hands.
Place the balls in a cool place until ready to cook.
Cook and serve
Just before serving the soup, carefully add the balls and boil for 1 minute.

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.
