Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Form the main bulk of the dish and soften into a tender, mild vegetable when cooked.
- White sauce
- Provides a creamy base that coats the cucumber and gives the sauce its body.
- Butter
- Adds richness and carries flavour as the cucumbers cook in the pan.
- Egg yolks
- Thicken the sauce as they gently cook, giving it a smooth, rich consistency.
The step that matters
Cooking the egg yolks gently. Egg yolks set when heated, so if the sauce boils after they go in it can curdle or turn grainy. Heating gently keeps the sauce smooth while it thickens.
