Why it works: Parsley and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Black Bean Soup
Ingredients
Directions
Prepare the beans
Soak the black beans overnight, then drain.
Add the parsley, celery root, bay leaf, peppercorns, and clove in a cheesecloth bag.
Cover with cold water and boil slowly until tender, adding water as needed.
Make the soup
Once soft, remove the seasonings and pass the beans through a sieve, mashing them with a spoon.
Add the stock to the mashed beans.
Melt the butter, stir in the flour, and gradually mix into the stock.
Season with salt and pepper.
Serve
In a tureen, add the sherry wine, lemon slice, egg balls, and diced egg white just before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Black beans
- Form the body of the soup when cooked and passed through a sieve.
- Soup stock
- Provides the liquid base that thins and flavours the mashed beans.
- Butter
- Melted with flour to make a roux that thickens the soup.
- Flour
- Combined with melted butter to thicken the stock smoothly.
- Sherry wine
- Adds aromatic depth and a touch of acidity when added at serving.
The step that matters
Thickening with the butter and flour. Flour must be cooked briefly in the melted butter before liquid is added, and the stock should be added gradually while stirring. This prevents lumps and a raw floury taste, giving a smooth, evenly thickened soup.
Swap the beans
