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 ↓

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

  1. Preheat the oven to 400°F (200°C).

  2. Place the chopped meat in an earthen dish.

  3. Add salt, pepper, and hot water to the meat.

Assemble and bake

  1. Mix hot milk with the mashed potato and spread it on top of the meat.

  2. 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.

Swap the celery

How well each one fits the dish's main ingredients (meat, milk, potato, pepper):

  2. Rosemaryfits about as well
  3. Parsleyfits about as well
  4. Celerythe original

Fit is the average pairing score against meat, milk, potato, pepper. Candidates are from the same food group and used in at least 100 recipes.
