Why it works: Lamb and potato work together. They rank in the top 9% of all ingredient pairs, and cooks put them together in 520 recipes. Both carry 2-undecenal, which smells sweet. The science ↓
Lamb’s Fry
Ingredients
Directions
Prepare
Slice the lamb's fry and sprinkle it with flour.
Fry and simmer
Heat the butter in a frying pan and fry the lamb's fry quickly.
Transfer the fried lamb's fry to a stew pan.
Pour the stock into the frying pan and heat it.
Once hot, pour the stock over the lamb's fry and simmer gently for 30 minutes.
Mix the flour with cold water to create a slurry and thicken the gravy.
Let the gravy boil, then serve the lamb's fry garnished with mashed potatoes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lamb's fry
- Is the main protein, cooked quickly and then simmered until tender.
- Stock
- Forms the liquid base of the gravy and carries the savoury flavour.
- Dripping or butter
- Fat for frying, adding richness and browning to the lamb's fry.
- Flour
- Thickens the gravy as a slurry with cold water.
The step that matters
Adding the flour slurry to the gravy. Flour must be mixed with cold water first so it disperses without lumps. Stirring it into hot liquid dry or without enough mixing causes clumps. The gravy then needs to boil so the starch swells and thickens properly.
Swap the potato
How well each one fits the dish's main ingredients (lamb, butter, flour):
- Okrafits about as well
- Shallotfits about as well
- Potatothe original
- Asparagusfits about as well
Fit is the average pairing score against lamb, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
