Why it works: Potato and tomato match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 2,798 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Boiled Tongue
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Soak the tongue overnight.
Place the tongue in a pot and cover with cold water.
Boil until tender.
Cook and finish
For cold serving, let it cool in the boiling water.
For warm serving, remove from water.
For warm serving, skin the tongue.
For warm serving, glaze with beaten egg and bread crumbs.
Bake in a 400°F (200°C) oven until slightly crusted.
Serve with mashed potatoes or tomato sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tongue
- Is the main protein, becoming tender through long gentle boiling.
- Egg
- Beaten egg binds the bread crumbs and helps them brown in the oven.
- Bread crumbs
- Form a crisp, golden crust when baked over the glazed tongue.
The step that matters
Boil until tender. Tongue is a tough muscle rich in connective tissue. Gentle simmering over a long time converts collagen to gelatin, which makes the meat tender. Boiling too hard can toughen the outer meat and break the skin.
Swap the potato
How well each one fits the dish's main ingredients (egg, bread, tomato, sauce):
- Capsicumfits better
- Asparagusfits better
- Cucumberfits better
- Potatothe original
Fit is the average pairing score against egg, bread, tomato, sauce. Candidates are from the same food group and used in at least 100 recipes.
