Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- String beans
- The main vegetable, cooked slowly until tender in the pork and seasonings.
- Fresh fat pork
- Renders fat and flavour into the beans as they simmer.
- Cream
- Adds richness and a smooth, velvety body to the finished beans.
- Egg yolks
- Thicken the cream mixture gently and bind it to the beans.
- Butter
- Adds fat for richness and a silky mouthfeel.
The step that matters
Adding the cream and egg yolk mixture. Raw egg yolks thicken when heated, but if the beans are too hot or the mixture is added carelessly it can scramble into lumps. Toss gently and keep the heat low so the sauce turns smooth.
