Why it works: Celery and pepper match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 16,012 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Cottage Pie
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Place the chopped meat in an earthen dish.
Add salt, pepper, and hot water to the meat.
Assemble and bake
Mix hot milk with the mashed potato and spread it on top of the meat.
Bake until the potato is brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chopped meat
- Forms the savoury base layer that gives the pie its body and flavour.
- Mashed potato
- Forms the topping that browns in the oven, adding a crisp, golden surface.
- Hot milk
- Makes the mashed potato softer and smoother so it spreads easily over the meat.
- Hot water or gravy
- Adds moisture to the meat so it does not dry out while baking.
The step that matters
Spreading the potato over the meat. Hot mashed potato spreads more easily and stays smooth, and covering the meat fully helps it stay moist while the potato browns on top.
