Why it works: Parsley and onion are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 25,843 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Steak Rolls
Ingredients
Directions
Prepare the rolls
Cut the steak into strips 2 inches wide and 4 inches long.
Sprinkle the strips with salt, chili powder, parsley, and onion.
Roll the strips tightly and secure with toothpicks.
Coat and fry
Dip each roll in the beaten egg, then roll in cracker crumbs.
Fry in a pan with plenty of hot fat until golden brown.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Onion and egg barely smell alike, yet cooks put them together in 23,333 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Round steak
- Forms the wrapped outer layer and cooks into tender, savory meat when rolled thin.
- Beaten egg
- Acts as a binder so the cracker crumbs stick to the outside of each roll.
- Cracker crumbs
- Form a crisp, golden coating that browns when fried.
- Onion
- Adds sweetness and aroma to the savory filling as it cooks.
The step that matters
Securing the rolls before frying. If the rolls are not rolled tightly and fastened with toothpicks, they can unroll in the hot fat and the filling can leak out. Tight rolling keeps the layers together while the surface sets and browns.
Swap the onion
How well each one fits the dish's main ingredients (parsley, egg):
- Shallotfits better
- Chivefits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against parsley, egg. Candidates are from the same food group and used in at least 100 recipes.
