Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chicken or veal knuckle
- Provides the meat and rich flavor base for the soup as it simmers.
- Onions
- Browning in fat adds sweetness and savory depth to the broth.
- Lard
- Fat for frying that helps the meat and onions brown well.
- Gumbo
- Thickens the soup and adds body as it cooks down over hours.
- Tomatoes
- Add moisture and acidity that brighten and round out the soup.
The step that matters
Boil slowly for 4-5 hours. A gentle simmer lets collagen and flavor slowly release from the meat and vegetables. A hard boil can toughen the meat and cloud the broth, and frequent stirring keeps solids from scorching on the bottom of the pot.
Swap the onion
