Why it works: Green beans and pepper work together. They rank in the top 13% of all ingredient pairs, and cooks put them together in 369 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ingredients
Directions
Prepare the beans
Trim the ends off the beans and remove the strings.
Cut the beans into 1-inch pieces and soak them in cold water with a little salt.
Cook and serve
In a saucepan, bring 2 quarts of water to a boil with ½ tablespoon of coarse sea salt and 1 teaspoon of powdered sugar.
Once boiling, add the beans and cook until they sink in the water.
Drain the beans in a colander and transfer to a hot dish.
Season with butter, pepper, and additional salt to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green beans
- Form the main body of the dish, providing the tender-crisp texture once cooked.
- Powdered sugar
- Adds a touch of sweetness to the cooking water, mildly balancing the salt.
- Butter
- Adds richness and a silky coating that carries flavour over the cooked beans.
The step that matters
Cooking the beans in boiling salted water. Beans cooked in a rapidly boiling, well-salted pot keep their bright green colour and tender-crisp bite. Overcooking breaks down cell walls and turns them dull and soft, so they should be checked as soon as they sink.
Swap the green beans
How well each one fits the dish's main ingredients (sugar, butter, pepper):
- Capsicumfits better
- Potatofits better
- Sweet potatofits better
- Green beansthe original
Fit is the average pairing score against sugar, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
