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. Boil the diced turnip until tender and cook the soaked tapioca until clear.

Layer and bake

  1. In a buttered baking dish, layer the chopped onion, followed by the tapioca, potatoes, turnip, and tomato, adding a little butter on each layer. Repeat the layering until the dish is full, finishing with a layer of potatoes on top.

  2. Bake in a 400°F (200°C) oven for one hour. Remove the cover during the last 15 minutes and add a layer of bread crumbs to brown.

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

What each ingredient does

Potatoes
Form the bulk of the dish and become tender and starchy as they bake.
Tapioca
Thickens the juices as it cooks, giving the layers a soft, slightly gelled texture.
Stewed tomato
Adds moisture and acidity that flavour the layers as they cook down.
Turnip
Adds body and a mild, slightly peppery flavour while staying tender in the layers.
Bread crumbs
Form a topping that browns in the oven once the cover is removed.

The step that matters

Removing the cover for the last 15 minutes. Covered baking traps steam so the layers cook through. Uncovering lets surface moisture evaporate and the bread crumbs brown; removing the cover too early can dry the dish, while leaving it on prevents browning.

Swap the turnip

How well each one fits the dish's main ingredients (onion, tomato, potato, butter, pepper, bread):

  1. Capsicumfits better
  2. Chivefits better
  3. Carrotfits better
  4. Turnipthe original

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