Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Lamb’s Fry
Ingredients
Directions
Prepare and fry
Slice the liver and sprinkle it well with flour.
Heat the butter in a frying pan and fry the liver quickly.
Transfer the fried liver to a stew pan.
Make the gravy and serve
Pour the stock into the frying pan and heat it.
Once hot, pour the stock over the liver 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 dish up the liver and garnish with mashed potatoes.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lamb's liver
- Forms the main protein; its texture depends on brief frying and gentle simmering.
- Stock
- Provides the liquid that becomes the gravy and keeps the liver moist.
- Flour
- Thickens the gravy as it cooks and helps lightly coat the liver for browning.
- Dripping or butter
- Conducts heat for frying and adds fat for browning and rich flavour.
The step that matters
Fry the liver quickly. A brief fry over good heat browns the outside and keeps the inside tender. Prolonged cooking toughens liver proteins and makes it dry and grainy, so the frying time should be kept short.
