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 Corned Beef Hash
Ingredients
Directions
Prepare the hash
Combine potatoes, corned beef, and onion.
Add 1/2 cup cream and 1 tablespoon melted butter.
Season and mix well.
Place mixture in a buttered oblong baking dish.
Using the bottom of a custard cup, make six indentations in the hash, dot each with butter, using 1 tablespoon in all.
Bake with the eggs
Bake at 450 for 15 minutes.
Remove from oven and break one egg into each indentation.
Season and cover each egg with 1 teaspoon of cream and dot with remaining butter.
Bake at 350 until the eggs are set, 15–20 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 hash and give it a soft, starchy body.
- Corned beef
- Provides the savory, salty meat flavor that defines the hash.
- Eggs
- Set during baking to form soft cooked pools that hold the hash together.
- Cream
- Adds moisture and richness, keeping the hash and eggs tender as they bake.
- Butter
- Adds fat and richness and helps the top brown in the oven.
The step that matters
Baking the eggs at the second temperature. Eggs continue to cook from residual heat, so pulling them when the whites are just set and yolks still soft keeps them tender. Overbaking turns the yolks chalky and dry.
