Why it works: Cream and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Beans, Boiled French
Ingredients
Directions
Cut off the heads and tails of the beans, and remove the strings by cutting a thin strip on each side.
Divide each bean into 4 or 6 pieces and place them in cold water with a little salt dissolved in it.
In a saucepan, bring water to a boil and add salt and baking soda.
Add the beans to the boiling water and cook uncovered until tender, ensuring they do not get smoked.
Once tender, drain the beans in a colander.
In a stewpan, combine the beans with stock, finely minced herbs, and sugar. Stew until tender and the liquid has reduced slightly.
Beat the egg yolk with the cream and add to the beans, heating until just simmering.
Serve hot with plain melted butter.
