Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peanut butter
- Provides the main flavor and body, thickening the dressing into a creamy paste.
- Hard-boiled eggs
- Their rubbed-smooth yolks emulsify with the milk and peanut butter, giving a smooth, rich texture.
- Lemon juice
- Adds acidity that brightens the rich peanut butter and balances the sugar.
- Sugar
- Adds sweetness to balance the acidity of the lemon and the saltiness of the seasoning.
- Milk
- Thins the peanut butter so it can be beaten into a smooth, pourable dressing.
The step that matters
Rubbing the egg yolks smooth. Lumps of yolk won't blend into the dressing, leaving a grainy texture. Pressing the yolks through a sieve or mashing them fine lets them emulsify evenly with the other ingredients.
Swap the peanut
How well each one fits the dish's main ingredients (butter, sugar, milk, lemon, egg, pepper):
