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 ↓
Baked Hash
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
In a pan, combine the meat, potatoes, and grated onion.
Add a little butter and mix well.
Bake and serve
Bake for thirty minutes.
When done, fold it like an omelet and turn onto a hot dish.
Garnish with points of toast and parsley.

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 hash and provide starch that becomes tender and soft when baked.
- Meat
- Provides savory flavor and substance, binding with the potatoes as the hash bakes.
- Onion
- Adds aroma and sweetness as it cooks, contributing moisture and flavor to the mixture.
- Butter
- Adds fat for richer flavor and helps the surface brown in the oven.
The step that matters
Fold it like an omelet and turn onto a hot dish. The hash must be fully set and firm after baking before folding, otherwise it will break apart. Turning it onto a hot dish keeps it warm for serving.
Swap the onion
How well each one fits the dish's main ingredients (meat, potato, butter):
- Onionthe original
- Asparagusfits about as well
- Chivefits about as well
- Leekfits less well
Fit is the average pairing score against meat, potato, butter. Candidates are from the same food group and used in at least 100 recipes.
