Why it works: Beef and potato are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 2,052 recipes. Both carry sotolon, which smells curry, maple. The science ↓
Hash, with Potatoes
Ingredients
Directions
Prepare
Remove bones from the cold beef and chop it finely.
Boil potatoes with skins on, then cool and chop them coarsely.
Cook
In a skillet, combine the chopped beef and potatoes with melted butter and a little hot water.
Season to taste and stir until cooked through.
For a crispy texture, let it cook longer to form a crust on the bottom, then serve on a flat dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold beef
- Forms the savoury body of the hash and provides most of its flavour.
- Potatoes
- Bulk and starch that bind the hash and crisp into a crust when left to brown.
- Butter or clarified drippings
- Adds fat for richness and helps the bottom brown in the skillet.
The step that matters
Letting the bottom form a crust. Pressing the hash and leaving it undisturbed in the skillet lets the surface brown through the Maillard reaction, which creates the crisp texture. Stirring too often or too early keeps it soft and steamed.
Swap the potato
How well each one fits the dish's main ingredients (beef, butter):
- Potatothe original
- Onionfits about as well
- Chivefits less well
- Tomatofits less well
Fit is the average pairing score against beef, butter. Candidates are from the same food group and used in at least 100 recipes.
