Why it works: Parsley and thyme match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,057 recipes. Both carry cuminaldehyde, which smells Spicy, cumin. The science ↓
Beans, French, Boiled
Ingredients
Directions
Prepare the beans
Trim the ends and stalks of the young beans and remove the strings.
Place the beans in a large saucepan of boiling water with salt.
Boil the beans for 15 minutes if young, or 20-25 minutes if old, until tender.
Drain the beans and return them to the saucepan.
Make the sauce
Melt the butter in the saucepan, then stir in the flour to thicken.
Add the chopped parsley, thyme, chives, and stock; season with salt and pepper.
Stew for 10 minutes, then thicken with beaten eggs mixed with milk or cream.
Serve
Serve quickly, adding lemon juice if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- French beans
- Provide the main vegetable body and tender texture of the dish.
- Butter
- Adds richness and fat, carrying flavour through the sauce.
- All-purpose flour
- Thickens the butter and stock into a smooth, coating sauce.
- Eggs
- Set gently in the warm sauce to thicken and enrich it.
- Stock
- Forms the liquid base of the sauce and adds savoury flavour.
The step that matters
Thicken with eggs gently. Eggs set when heated. If the sauce is too hot or boiling when they go in, they can scramble and turn grainy, so add them off the heat or at a low simmer and stir steadily.
Swap the beans
How well each one fits the dish's main ingredients (butter, flour, parsley, thyme, chive, egg, milk):
- Chestnutfits better
- Chickpeafits better
- Lentilsfits about as well
- Beansthe original
Fit is the average pairing score against butter, flour, parsley, thyme, chive, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
