Why it works: Thyme and pepper are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 11,585 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Turtle Bean Soup
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Wash the black beans and place them in a pot with 3 quarts of water.
Boil the beans until thoroughly soft.
Rub the pulp through a colander and return it to the pot.
Wrap the thyme in a clean cloth and add it to the pot.
Let it boil for 10 minutes for flavor.
Slice the hard boiled eggs and drop them into the soup.
Add butter, salt, and pepper to taste.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Black beans
- Form the main body of the soup and, once pulped, thicken it.
- Dried thyme
- Adds an herbal aroma that flavors the broth as it simmers.
- Hard boiled eggs
- Add soft, mild richness and bulk to the finished soup.
- Butter
- Adds fat, giving the soup a smoother, rounder mouthfeel.
The step that matters
Rub the pulp through a colander. Beans must be fully soft before pressing, because firm skins and bits will not pass through the colander and leave the soup grainy.
Swap the beans
How well each one fits the dish's main ingredients (thyme, egg, butter, pepper):

Fit is the average pairing score against thyme, egg, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
