Why it works: Flour and butter 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 ↓
Boiled Corned Beef
Ingredients
Directions
Prepare the beef
Soak the corned beef in clean cold water for 5 to 6 hours to remove excess salt.
Wipe the beef and place it in a pot, covering it with cold water.
Boil gently for 25 minutes per pound.
Make the sauce
Once cooked, remove the pot from the heat and let the beef sit in the pot while you prepare the sauce.
Strain 1 cup of the cooking liquid into a saucepan and heat it.
Mix 1 tablespoon of flour with cold water, then stir it into the boiling liquid along with 1 tablespoon of butter.
Beat the mixture smooth before adding the juice of 1 lemon.
Serve the sauce in a gravy dish and place the beef on a hot platter, allowing excess liquid to drain.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Corned beef
- Provides the main meat, which becomes tender through long gentle simmering.
- Flour
- Thickens the cooking liquid into a smooth sauce as it heats.
- Butter
- Adds richness and a silkier texture to the sauce.
- Lemon juice
- Adds acidity that brightens the flavour of the rich sauce.
The step that matters
Beating the flour mixture smooth. Flour mixed with cold water must be fully dispersed before or as it meets hot liquid; otherwise it clumps into lumps that stay in the sauce. Stirring the flour into boiling liquid helps it thicken evenly.
Swap the lemon
How well each one fits the dish's main ingredients (beef, flour, butter):

Fit is the average pairing score against beef, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
