Why it works: Kidney beans and cheese share more aroma than cooks usually use. They rank in the top 8% of all ingredient pairs, and 76 recipes mention both. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
The recipe
Ingredients
Contains: egg, milk (auto-detected from the ingredients and method; we can miss things, so check labels)
Also mentioned in the method: egg
Directions
Prepare the beans
Scald the cheese whey.
Make a brine strong enough to float an egg.
Add the fresh kidney beans to the whey brine.
Let the beans sit until they turn bright yellow.
Drain the beans through a sieve.
Dry the beans with a coarse cloth.
Pickle and colour
Place the beans in a brass pan.
Cover the beans with alegar.
Add dill to the beans.
Cover tightly, sealing the edges with paper to trap steam.
Set the pan over low heat until the beans turn green.
Remove the beans from the pickle.
Jar and finish
Place the beans in a jar.
Boil fresh alegar with black pepper, Jamaica pepper, and sliced ginger.
Add the boiled alegar to the jar with the beans.
Ensure the beans are well covered.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Young kidney beans
- Are the main vegetable, becoming tender and firm as they pickle in the vinegar.
- Alegar (good vinegar)
- Provides the acidity that preserves the beans and gives the pickle its sharp flavour.
- Cheese whey
- Used in the brine to help the beans change colour during soaking.
- Dill
- Adds a fresh herbal aroma to the pickled beans.
The step that matters
Set the pan over low heat until the beans turn green.. Gentle heat changes the bean colour without cooking them through. Higher heat or longer cooking can turn them dull and soft, and the bright colour is lost.
Flavor stand-ins for the ginger

Fit is the average pairing score against kidney beans, cheese, whey, dill, vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
