Potato-flour Cake

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Make the batter

  1. Mix the potato flour with the powdered sugar.

  2. Roll the mixture with a bottle.

  3. Beat the yolks and whites of the eggs separately, then combine them.

  4. Whisk all ingredients together until light and fluffy.

Bake

  1. Preheat the oven to 350°F (175°C).

  2. Grease a tin and the paper.

  3. Pour the batter into the prepared tin and bake for 30 minutes.

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

What each ingredient does

Potato flour
Forms the body of the cake and gives it a soft, tender crumb.
Eggs
Provide structure and lift, since the beaten whites trap air that expands in the oven.
Powdered sugar
Sweetens the cake and dissolves finely, giving a smooth texture.

The step that matters

Whisk the whites and yolks into the batter until light and fluffy. Beaten egg whites trap air that expands in the oven and gives the cake its rise. Overmixing or deflating the foam when combining makes the cake dense and heavy.

Swap the potato

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

  1. Chivefits better
  2. Leekfits better
  3. Shallotfits better
  4. Potatothe original

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