Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Warm the butter in a basin without letting it oil.
Beat the butter to a cream with a wooden spoon.
Gradually add the flour, then the sugar and flavoring.
Moisten the mixture with the well-beaten egg yolks.
Bake
Drop spoonfuls of the mixture onto buttered paper, leaving space between each.
Bake in a slow oven at 300°F (150°C) for 12 to 18 minutes, avoiding too much color.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air and gives the cakes a rich, tender texture.
- Flour
- Provides the structure that holds the cakes together as they bake.
- Sugar
- Adds sweetness and helps the butter cream, and contributes to browning.
- Egg yolks
- Moisten the batter and add richness, binding the mixture into a cohesive dough.
The step that matters
Bake in a slow oven and watch the color. Sugar and proteins brown quickly with heat, so a slow oven and close watching keep the cakes pale and evenly cooked rather than dark and dry.
Swap the ginger
The recipe marks ginger as optional. How well each one fits the dish's main ingredients (butter, flour, sugar, egg, currant):
- Cinnamonfits better
- Nutmegfits better
- Allspicefits better
- Gingerthe original
Fit is the average pairing score against butter, flour, sugar, egg, currant. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
