Oven, in the book's wordsA hot oven

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. Mix the baking powder with the flour in a bowl.

  2. Add the egg and milk, and beat the mixture for 20 minutes.

  3. Cut the beef into small pieces and grease a pie dish.

  4. Place the beef in the dish, chop the onion, and sprinkle it over the beef with pepper and salt.

  5. Pour the batter over the meat and immediately place it in a 400°F (200°C) oven.

Bake

  1. Once the batter has risen, move it to a cooler part of the oven and bake for 1 hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Flour
Forms the batter's structure as it sets around the meat.
Egg
Binds the batter and helps it set firm and rise.
Milk
Adds moisture and helps the batter bake tender and golden.
Baking powder
Releases gas in the oven, helping the batter rise.
Beef
Provides the main savoury filling, with fat that flavours the pan.

The step that matters

Heating the oven and pan before the batter goes in. The batter must hit a hot oven immediately so the baking powder starts releasing gas and the batter puffs before setting. A cold start leads to a flat, dense result.

Swap the onion

How well each one fits the dish's main ingredients (beef, flour, egg, milk, pepper):

  1. Capsicumfits better
  2. Potatofits better
  3. Asparagusfits better
  4. Onionthe original

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