Why it works: Thyme and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 3,973 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Bean Soup
Ingredients
Directions
Prepare the beans
Place the beans in a kettle and cover with water.
When boiling, stir in a small piece of baking soda and let boil briefly.
Drain the water and add fresh water with a small piece of pork.
Cook until the beans are tender.
Finish the soup
Remove the beans and press them through a colander into the cooking water.
Tie thyme in a small bag and add it to the pot to simmer for a few minutes.
Add the quartered hard-boiled eggs, sliced lemon, butter, salt, and pepper.
Add a piece of fresh raw beef until cooked through, but do not serve it in the soup.
Alternatively, add rich milk and butter.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beans
- Form the body of the soup once cooked and pressed, thickening the cooking water.
- Baking soda
- Raises the pot's alkalinity, which softens the bean skins and speeds tenderizing.
- Pork
- Adds savory, meaty flavor to the cooking water as the beans simmer.
- Butter
- Adds richness and fat that gives the soup a smoother mouthfeel.
- Lemon
- Adds acidity that brightens the flavor of the rich soup.
The step that matters
Adding baking soda to the boiling beans. Too much baking soda can make beans taste soapy or mushy, and it must be added in only a small amount while the water is boiling so the beans soften evenly without breaking down entirely.
Swap the beans
