Why it works: Lamb and egg match in chemistry and in kitchens. They rank in the top 15% of all ingredient pairs, and 1,189 recipes mention both. Both carry 2-nonenal, which smells fatty, green. The science ↓
The recipe
Ingredients
Contains: egg (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare
Chop the cold lamb very fine.
Boil the potatoes until tender, then mash them finely.
Make the hash
Combine the mashed potatoes with the chopped lamb and enough Allemande sauce to achieve a hash-like consistency.
Season with coarse sea salt, black pepper, and a little ground mace, then heat the mixture.
Serve
Serve the hot hash on toast and top with a poached egg.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold lamb
- Provides the main meat and bulk of the hash.
- Potatoes
- Mashed to bind the lamb and give the hash a soft, moist texture.
- Allemande sauce
- Adds moisture and richness so the mixture holds together as a hash.
- Poached egg
- Adds richness and a soft, runny yolk that moistens the hash when broken.
The step that matters
Heating the hash after seasoning. Heating gently and stirring until the mixture is evenly hot lets the potato and sauce bind without scorching on the pan base, which would give a burnt taste.

Fit is the average pairing score against lamb, potato, sauce, pepper, egg. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
