Why it works: Potato and parsley match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and 2,855 recipes mention both. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
The recipe
Ingredients
Contains: egg, milk (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare the potatoes
Wash and peel the potatoes.
Slice them uniformly to about ¼ inch thick and spread on a clean cloth to remove moisture.
Fry and serve
Dissolve enough beef dripping in a frying pan until boiling.
Drop in the potato slices, ensuring they are completely covered by the fat.
Cook while turning them continuously until they are golden yellow.
Lift them from the fat and drain on blotting paper for 1-2 minutes.
Serve in a hot dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the starchy body of the dish, which turns tender inside while the surface crisps and browns.
- Beef dripping
- Fat for frying that conducts heat evenly and gives the potatoes a golden, savoury crust.
The step that matters
Cooking the slices in the fat while turning them. Slices must be fully submerged and turned constantly so heat reaches every side evenly. Uneven contact leads to patchy browning or greasy, undercooked pieces. Drying the slices first keeps the fat from spattering and helps the surface crisp.

Fit is the average pairing score against potato, egg, butter, beef. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
