Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 34,122 recipes mention both. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Rostii
Ingredients
Directions
Prepare the potatoes
Place potatoes in colander and rinse. Dry on paper towels.
In a large bowl, combine onion, flour and parsley. Stir in egg, egg-white, salt and pepper. Add potatoes and mix well.
Cook the pancakes
Spray a large non‑stick skillet with vegetable cooking spray. Heat skillet over medium‑high heat. Add 1 teaspoon of the butter.
Place about 3 tablespoons of potato mixture in skillet. Flatten into pancake with spatula. Make 3 more pancakes in skillet as directed.
Cook until browned on the bottom, about 7 minutes, pressing with spatula. Turn carefully; cook until golden on the other side, about 6 or 7 minutes.
Place on a plate and cover to keep warm. Repeat twice with the remaining butter and potato mixture.
Serve
Serve with applesauce, sour‑cream or yogurt.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Shredded starch that becomes tender inside and crisps on the outside when fried.
- Egg
- Binds the shredded potatoes and onion so the pancakes hold their shape.
- Egg white
- Adds extra binding protein, helping the pancake hold together without making it heavier.
- All-purpose flour
- Absorbs surface moisture and helps the grated mixture bind and brown.
- Onion
- Adds moisture and savory flavor that deepens as the pancake browns.
- Unsalted butter
- Adds fat for browning and a rich, nutty flavor on the crust.
The step that matters
Dry the potatoes before mixing. Shredded potatoes hold a lot of water. Excess moisture steams the pancakes instead of letting them brown and crisp, so drying them on paper towels is essential.

Fit is the average pairing score against potato, flour, parsley, egg, pepper, butter. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
