Why it works: Flour and raisin 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 ↓
Federal Cake
Ingredients
Directions
The book says “a cool oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Preheat the oven to 300°F (150°C).
Cream the sugar and butter together for at least 30 minutes until fine and grainy.
Add the grated nutmeg and the yolks of the eggs, beaten until thick and light colored. Mix well.
Gradually add the sifted flour and the sweet milk mixed with the dissolved baking soda, alternating between the two.
Fold in the Port wine, raisins, and citron.
Beat the egg whites until stiff and fold them into the batter.
Bake
Pour the batter into a prepared cake pan and bake in a cool oven.

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
- Eggs
- Yolks enrich and bind the batter, while whipped whites lighten its crumb.
- Butter
- Creamed with sugar, it traps air and gives the cake a tender, rich texture.
- Granulated sugar
- Creamed with butter, it helps build the aerated structure and adds sweetness.
- Pastry flour
- Its gentle protein content sets the cake's structure while keeping it tender.
- Baking soda
- Reacts with the acidic components in the batter to produce gas that helps it rise.
- Raisins
- Add chewy pockets of sweetness and moisture throughout the cake.
The step that matters
Folding in the beaten egg whites. Whites must be stiff but not overbeaten, and folded gently so the air they hold is not lost, which would leave the cake dense.
Swap the nutmeg
How well each one fits the dish's main ingredients (sugar, butter, milk, port wine, flour, egg, raisin):
- Cinnamonfits better
- Nutmegthe original
- Clovefits less well
- Allspicefits less well
Fit is the average pairing score against sugar, butter, milk, port wine, flour, egg, raisin. Candidates are from the same food group and used in at least 100 recipes.
