Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Beef Minced and Poached Eggs
Ingredients
Directions
Make the beef filling
Peel and finely chop the onion, then fry it in butter until golden brown.
Add flour to the onions and stir over heat for a few minutes.
Mince the beef, removing all skin and gristle, and add it to the saucepan.
Moisten the mixture with stock, season with salt and pepper, and cook gently for 20 minutes.
Assemble and serve
Make a high border of mashed potatoes in a small dish and pour the beef mixture into the center.
Poach the eggs in boiling water with a little salt and lemon juice, then trim them.
Place the poached eggs on the beef mixture, spaced evenly apart.
Garnish with toast and parsley, and serve very hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold roast beef
- Forms the main meaty body of the filling.
- Potatoes
- Mashed potato forms a firm border that holds the filling in place.
- Butter
- Fat for frying the onion, adding richness and browning flavor.
- Flour
- Thickens the stock and fat into a cohesive, spoonable filling.
- Eggs
- Poached eggs add soft, runny yolk richness on top of the filling.
The step that matters
Poach the eggs in gently simmering water. Eggs boiled too hard break apart and feather, while fresh eggs in gently simmering water hold their shape. The added salt and lemon juice help the whites set more quickly and neatly.
