Simnel Cake

Ingredients

Directions

The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Preheat the oven to 300°F (150°C).

Make the cake

  1. In a large bowl, mix the flour, sugar, baking soda, nutmeg, and currants.

  2. Add the butter, brandy, eggs, and vinegar, and mix until well combined.

  3. Spread a layer of the mixture in a prepared cake tin.

  4. Place a layer of almond paste on top, then add another layer of the cake mixture.

Bake and decorate

  1. Bake for four hours.

  2. Once baked, decorate with almond paste, preserved fruits, and royal icing.

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

What each ingredient does

Flour
Forms the structure that holds the dense fruit and layers together as the cake sets.
Eggs
Bind the mixture and set during baking, giving the cake its structure.
Butter
Adds fat for richness and a tender crumb.
Sugar
Adds sweetness and helps the crust brown during the long bake.
Baking soda
Reacts with the vinegar to release gas that helps the cake rise.
Currants
Add sweetness and moisture through the fruit cake.

The step that matters

Baking for four hours at a low temperature. A dense fruit cake needs a long, gentle bake so the centre cooks fully and sets before the outside darkens too much. Rushing it with higher heat can leave the middle wet or the crust burnt.

Swap the currant

How well each one fits the dish's main ingredients (flour, brandy, nutmeg, raisin, vinegar, almond, butter):

  1. Figfits better
  2. Vanillafits better
  3. Apricotfits better
  4. Currantthe original

Fit is the average pairing score against flour, brandy, nutmeg, raisin, vinegar, almond, butter. Candidates are from the same food group and used in at least 100 recipes.
