Royal Baking Powder Bread

Oven, in the book's wordsA rather hot oven

Ingredients

Directions

The book says “a rather hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Make the dough

  1. Sift together the flour, salt, sugar, and baking powder thoroughly.

  2. Rub in the cold boiled potato.

  3. Add enough water to form a dough.

Shape and bake

  1. Shape the dough and place it in a greased tin.

  2. Bake in a preheated oven at 400°F (200°C) for about 40 minutes.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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

What each ingredient does

Flour
Forms the main structure that holds the bread together as it bakes.
Baking powder
Releases gas when moistened and heated, lifting the dough so it rises.
Cold boiled potato
Adds moisture and softness to the crumb, helping the bread stay tender.
Sugar
Adds a little sweetness and helps the crust brown during baking.

The step that matters

Sifting the baking powder thoroughly. Baking powder must be evenly spread through the flour. Lumps leave pockets of concentrated acid and base, causing patchy rising and bitter spots.

Swap the potato

How well each one fits the dish's main ingredients (flour, sugar):

  1. Arrowrootfits better
  2. Beetrootfits better
  3. Sweet potatofits better
  4. Potatothe original

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