Why it works: Butter and sugar are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 98,233 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- String beans
- Form the main body of the dish, becoming tender when boiled.
- Baking soda
- Raises the water's alkalinity, helping the beans stay bright green.
- Butter
- Adds richness and fat, carrying flavor across the beans.
- Sugar
- Adds a light touch of sweetness to the butter.
The step that matters
Boil for the stated time only. Baking soda keeps beans green by making the water alkaline, but alkalinity also softens cell walls. Boiling too long leaves the beans mushy, so check them as the 20 to 25 minute window closes.
Swap the beans
How well each one fits the dish's main ingredients (butter, sugar):
- Almondfits better
- Pecansfits better
- Filbertfits better
- Beansthe original
Fit is the average pairing score against butter, sugar. Candidates are from the same food group and used in at least 100 recipes.
