Duff Pudding

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

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

  2. Butter a pudding dish.

  3. Place the quartered apples in the dish.

Make and bake

  1. In a bowl, mix the flour, sugar, cream of tartar, and baking soda.

  2. Add the beaten eggs and melted butter to the dry ingredients and mix well.

  3. Pour the mixture over the apples in the dish.

  4. Bake until set and golden brown.

Serve

  1. Serve with sauce.

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

What each ingredient does

Flour
Provides the structure that sets the batter around the apples as it bakes.
Eggs
Bind the batter and help it set into a firm, sliceable pudding.
Butter
Adds richness and moisture, and helps the pudding brown at the edges.
Sugar
Sweetens the batter and contributes to golden browning in the oven.
Cream of tartar
Acidifies the batter and works with baking soda to lift and lighten the crumb.
Baking soda
Reacts with the acidic cream of tartar to produce gas that makes the pudding rise.

The step that matters

Bake until set and golden brown. Underbaking leaves the batter wet and gummy, while overbaking dries the crumb. The pudding is ready when the centre is set and the top is golden.

Swap the apple

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

  1. Vanillafits better
  2. Figfits better
  3. Coconutfits better
  4. Applethe original

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