Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tongue
- The main ingredient; slow simmering in the sauce keeps it tender and moist.
- Tomatoes
- Form the body of the sauce and add moisture and acidity.
- Onion
- Provides the savory base flavor of the sauce as it cooks down.
- Allspice
- Adds a warm, aromatic spice note to the sauce.
The step that matters
Simmering the tongue slowly in the sauce. Gentle, slow simmering lets the connective tissue in the tongue break down gradually, giving tender meat. A hard boil can toughen the surface and make the meat stringy.
