Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Peel and boil the potatoes until tender.
Cut the potatoes into 1-inch blocks.
Make the gravy
In a saucepan, combine milk, butter, flour, salt, and pepper.
Cook until the gravy thickens like cream.
Pour the gravy over the potatoes.
Bake and serve
Top with grated crackers and bake at 400°F (200°C) until browned.
Garnish with parsley leaves and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the dish and give it a tender, starchy body.
- Milk
- Provides the liquid that becomes the creamy gravy and keeps the potatoes moist.
- Flour
- Its starch thickens the milk into a smooth gravy as it cooks.
- Butter
- Adds fat for richness and a silky mouthfeel in the gravy.
- Grated crackers
- Toast on top in the oven, adding browning and a crisp finish.
The step that matters
Cook the gravy until it thickens. Flour only thickens fully once heated and its starch swells in the liquid. If the gravy is pulled off too early, it stays thin and can taste raw and floury, so it should be cooked until it coats a spoon like cream.
Swap the parsley
How well each one fits the dish's main ingredients (potato, milk, butter, flour, pepper):
- Parsleythe original
- Nutmegfits about as well
- Cinnamonfits about as well
- Thymefits about as well
Fit is the average pairing score against potato, milk, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
