Why it works: Raisin and flour match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Christmas Cake

Oven, in the book's wordsA very slow oven

Ingredients

Directions

The book says “a very slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

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

Make the batter

  1. In a large bowl, beat together the sugar, butter, and eggs until well combined.

  2. Add the sweet milk, raisins, citron, currants, and spices.

  3. Sift in the flour with the baking powder and mix until just combined.

Bake

  1. Pour the batter into a prepared cake pan and bake for 4 to 5 hours.

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 batter together as it bakes.
Eggs
Bind the batter and add structure and richness as they set.
Butter
Adds fat for tenderness and a rich texture.
Sugar
Sweetens the cake and helps it brown during the long bake.
Baking powder
Releases gas that helps the cake rise and lighten.
Raisins
Add sweetness, chewy texture and moisture to the fruit cake.

The step that matters

Mix the flour in until just combined. Once flour meets liquid, gluten begins to form; overmixing makes the cake tough and dense, so stop as soon as no dry flour streaks remain.

Swap the clove

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

  1. Cinnamonfits better
  2. Nutmegfits better
  3. Allspicefits about as well
  4. Clovethe original

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