Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Matzo Balls
Ingredients
Directions
Make the mixture
Chop and fry the onion in butter or fat until brown.
Soak the matzos in cold water until soft, then drain.
Add the soaked matzos to the onion and stir until the mixture does not stick to the pan.
Remove from heat and add the beaten eggs and chopped parsley.
Season with pepper, coarse sea salt, ginger, and nutmeg.
Add enough matzo or cracker meal to hold the mixture together, using as little as possible.
Shape and cook
Shape the mixture into small balls and drop them into boiling soup 15 minutes before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Matzos
- Soaked matzo provides the bulk and starch that give the balls their body.
- Eggs
- Eggs bind the mixture and set when cooked, holding the balls together.
- Butter or fat
- Fat coats the onion and adds richness and flavor to the mixture.
- Onion
- Frying the onion until brown adds sweetness and savory depth.
- Matzo or cracker meal
- Dry crumbs absorb moisture and firm the mixture so it holds its shape.
The step that matters
Stirring the matzo and onion mixture. Cooking the soaked matzo with the onion drives off excess moisture so the mixture does not stick to the pan. Adding too much crumb later makes the balls dense and heavy, so use only as much as needed to hold them together.
Swap the onion
How well each one fits the dish's main ingredients (butter, egg, parsley, pepper, ginger, nutmeg):
