Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lamb shoulder
- Provides the main meat, whose fat is trimmed away before cooking.
- Carrots
- Add sweetness and body to the cooking liquid as they soften.
- Onion
- Adds aroma and savoury depth to the cooking liquid.
The step that matters
When half done, add the salt. Salt added partway through boiling seasons the meat and liquid while the lamb is still firm enough to absorb it, so timing matters for an even seasoning.
