Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and carries the flavour of the herbs and spices.
- Oil
- Keeps the butter from burning and helps the sauce coat the potatoes.
- Flour
- Lightly thickens the sauce so it clings to the potatoes.
- Potatoes (in the method)
- Form the body of the dish and soak up the sauce.
- Lemon juice or vinegar
- Adds acidity that brightens the rich butter and oil.
The step that matters
Toss the potatoes gently without boiling. Vigorous stirring or boiling breaks the cut potato pieces apart and turns them mushy. Gentle tossing keeps them intact while they absorb the sauce.
Swap the onion
