Why it works: Onion and mustard match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 9,259 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Beef Tongue
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the tongue
Boil the tongue in salt water until tender.
Remove from water, strip the skin, and trim around the roots.
Make the gravy
In a saucepan, melt the butter over low heat.
Add flour, chopped onion, salt, and pepper; cook until the butter boils.
Add the tongue and brown it on all sides.
Remove the tongue and keep it warm on a hot dish.
To the gravy, add red wine, mustard, and walnut catsup; mix well.
Return the tongue to the gravy and simmer for 10 minutes, covered.
Serve
Slice the tongue into thick pieces before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef tongue
- Forms the main meat, which becomes tender through boiling and then simmering in the gravy.
- Butter
- Provides fat for browning the tongue and enriching the gravy.
- Flour
- Thickens the butter and onion mixture into a gravy that coats the tongue.
- Red wine
- Adds acidity and depth of flavour to the gravy.
- Mustard
- Adds sharp, tangy flavour that balances the richness of the gravy.
The step that matters
Browning the tongue. Searing the tongue on all sides in the butter builds browned flavour through the Maillard reaction. Browning before simmering gives the gravy more depth and colour.
