Why it works: Parsley and pepper 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 ↓
To Bake
Ingredients
Directions
The book says “a brisk oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the potatoes
Boil the sliced potatoes in water with salt until soft.
Drain the water.
Mash the potatoes.
Make the mixture
In a bowl, mix flour and eggs to create a batter.
Combine the mashed potatoes with the batter and mix well.
Pour the mixture into a buttered baking dish.
Mix in soaked bread crumbs, sweet cream, chopped parsley, and cayenne pepper.
Bake the potato bake
Cover the top with bread crumbs.
Bake at 350°F (175°C) for 30 minutes.
Add minced sausage or other meat to the mixture before baking.
Bake the potato slices
Place potato slices on a greased baking sheet.
Bake at 400°F (200°C) for 20 minutes.
Add a small piece of bacon on each slice if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the bulk and starch that gives the bake its soft, sliceable body.
- Eggs
- Bind the mixture and help it set firm as it bakes.
- Flour
- Thickens the batter and helps hold the potatoes together.
- Bread crumbs
- Add texture and a browned, crisp top layer when baked.
- Sweet cream
- Adds moisture and richness, keeping the interior tender.
The step that matters
Drain the water. Excess water left in the boiled potatoes dilutes the mash and makes the bake soggy and loose, so drain them well before mashing.
Swap the potato
How well each one fits the dish's main ingredients (flour, egg, bread, cream, parsley, pepper, meat):
- Shallotfits better
- Spinachfits better
- Leekfits about as well
- Potatothe original
Fit is the average pairing score against flour, egg, bread, cream, parsley, pepper, meat. Candidates are from the same food group and used in at least 100 recipes.
