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 5–6 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.
Remove the pot from heat.
Let the pot sit in the sink with the meat inside.
Make the sauce
Strain a large cup of the cooking liquid into a saucepan.
Bring the strained liquid to a boil.
Mix the tablespoon of flour with cold water.
Stir the flour mixture into the boiling liquid along with a spoonful of butter.
Beat the mixture smooth.
Add the lemon juice.
Serve
Serve the sauce in a gravy dish.
Place the beef on a hot platter.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Corned beef
- Supplies the main meat, which is cooked gently until tender.
- Flour
- Thickens the strained cooking liquid into a smooth sauce.
- Butter
- Adds richness and a glossy finish to the sauce.
- Juice of a lemon
- Adds acidity that brightens the flavour of the sauce.
The step that matters
Stirring the flour mixture into the boiling liquid. Flour mixed only with cold water and then added to hot liquid can clump; mixing it smooth first and beating the sauce helps it thicken evenly.
Swap the lemon
How well each one fits the dish's main ingredients (beef, flour, butter):
- Raisinfits better
- Coconutfits better

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