Why it works: Onion and chicken are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 17,814 recipes. Both carry gamma-nonanolactone, which smells coconut, sweet. The science ↓
Oyster Gumbo
Ingredients
Directions
Make the roux and base
In a large pot, heat the lard until boiling.
Stir in the flour and cook until browned, stirring constantly to prevent burning.
Add the sliced onion and let it brown.
Fry the chicken in the lard and onion mixture until cooked.
Add enough water to make a soup base and let it cook for five hours.
Finish and serve
One hour before serving, add the oysters with their liquor.
Just before serving, stir in the gumbo filee a small amount at a time, mixing it with a cup of the liquid to prevent lumps.
Bring the soup to a boil after adding the filee, then season with salt and pepper to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Browned in the lard, it thickens the soup and adds a toasty, nutty flavour.
- Lard
- Fat for browning the flour and onion and frying the chicken, carrying flavour through the pot.
- Onion
- Browned in the fat, it adds sweetness and savory depth to the soup base.
- Chicken
- Simmered for hours, it releases meat flavour and richness into the soup.
- Oysters
- Added near the end so they stay tender while their liquor adds briny flavour.
- Gumbo filee
- Ground sassafras that adds a distinctive earthy aroma and thickens the soup when stirred in.
The step that matters
Stirring the flour while it browns. Flour can scorch quickly in hot fat. Constant stirring keeps it browning evenly, giving a rich colour and flavour without a bitter, burnt taste that would spoil the whole pot.
