Why it works: Corn and potato match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 938 recipes. Both carry (e)-2-octenal, which smells fatty, green. The science ↓
Corn Beef Hash
Ingredients
Directions
The book says “a hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Drop the corned beef into boiling water and simmer for 30 minutes per pound.
When cold, chop the corned beef and cooked potatoes coarsely.
Make the hash
Butter the bottom of a skillet.
Add the meat and potato mixture to the skillet.
Season with salt and pepper.
Add the butter and milk.
Place the skillet in a 350°F (175°C) oven for 30 minutes.
Stir the hash every 10 minutes.
Brown and serve
Reserve half the butter for browning.
Melt the reserved butter in a frying pan.
Add the mixture to the pan.
Cook without stirring until browned underneath.
Fold and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Corned beef
- Provides the main savory flavour and chewy meat texture of the hash.
- Cooked potatoes
- Supply starch that helps bind the hash and form a crisp browned crust.
- Butter
- Adds richness and flavour, and helps the surface brown in the pan.
- Milk
- Adds moisture that softens the mixture as it bakes.
The step that matters
Cook without stirring until browned underneath. Leaving the hash undisturbed lets its underside touch the hot pan long enough to brown and form a crust. Stirring too early breaks up that contact, so the hash stays soft and pale instead of crisp.
Swap the potato
How well each one fits the dish's main ingredients (corn, beef, butter, pepper, milk):
- Potatothe original
- Capsicumfits about as well
- Tomatofits less well
- Carrotfits less well
Fit is the average pairing score against corn, beef, butter, pepper, milk. Candidates are from the same food group and used in at least 100 recipes.
