Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Provide the main body of the dish, softening as they simmer in the gravy.
- Egg yolks
- Thicken the cream and gravy mixture into a smooth, lightly set sauce.
- Cream
- Adds richness and softness, mellowing the sauce with fat.
- Poached eggs
- Add a soft, set-egg topping that contrasts with the cooked cucumber.
- Lemon juice
- Adds brightness and acidity that balances the rich cream and yolks.
The step that matters
Stir in the beaten egg yolks with the cream. Egg yolks thicken when heated gently but can scramble if the mixture is too hot or added too quickly. Stir steadily off intense heat so the sauce thickens smoothly rather than curdling.
Swap the lemon
How well each one fits the dish's main ingredients (cucumber, ham, onion, clove, egg, cream):
- Avocadofits better
