Why it works: Onion and carrot are a kitchen classic. They rank in the top 6% of all ingredient pairs, and 21,601 recipes mention both. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Ox Tongue, to Collar
Ingredients
Directions
Cook the tongue
Boil the tongue gently with onion, carrot, herbs, and optional spices for 3–5 hours.
Remove the tongue from the liquid and skin it carefully to avoid holes.
Cut off any excess fat if desired.
Shape and set
While still hot, roll the tongue tightly with the tip inside and tie it securely with tape.
Place a plate on top and add weights to keep it in shape until it cools.

What each ingredient does
- Ox tongue
- Is the main meat, which becomes tender and firm enough to slice after slow simmering and pressing.
The step that matters
Skinning the tongue carefully. Skinning while the tongue is still warm keeps the surface intact, since tearing exposes the meat and lets juices and fat escape, leaving holes in the finished roll.
