Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Hash Browns
2–4Ingredients
Directions
Prepare the potatoes
Grate the raw potatoes with a cheese grater, place them into a bowl and cover completely with water. Let sit for 10 minutes.
Drain the grated potatoes well; if this is not done thoroughly the potatoes will steam instead of fry.
Mix in chopped onions by hand.
Mix the egg or flour into the hash brown mixture evenly. This will allow the hash browns to stay together when frying.
Fry the hash browns
Place a large frying pan on medium‑high heat and add enough oil to provide a thin coating over the entire bottom of the pan.
When the oil has come up to temperature, apply a large handful of potatoes to the pan and reshape into a patty that is about ¼–½ inch (6–12 mm) thick. The thinner the patty, the crispier the hash browns will be throughout.
Flip when they are crisp and brown on the cooking side. They should also stick together nicely before they are flipped. This should take about 5–8 minutes.
Cook the other side until it is brown and crispy. This should take another 3–5 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the patty, providing the starch that fries into a crisp exterior.
- Flour or egg
- Binds the grated potato so the hash browns hold together while frying.
- Onion
- Adds savory flavor and aroma to the potatoes.
The step that matters
Drain the grated potatoes well. Surface water turns to steam in the hot pan, so the potatoes steam instead of frying and fail to crisp. Thorough draining lets the surface brown.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (potato, flour):
- Chivefits better
- Arrowrootfits better
- Okrafits better
- Onionthe original
Fit is the average pairing score against potato, flour. Candidates are from the same food group and used in at least 100 recipes.
