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 ↓
Soda Cake for Tea
Ingredients
Directions
The book says “a brisk oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Warm the butter until melted and warm the milk.
In a bowl, mix the flour, baking soda, brown sugar, caraway seeds, currants, raisins, and candied peel.
Make the batter
Add the melted butter, warm milk, and eggs to the dry ingredients. Stir until well combined.
Pour the batter into a well-greased tin.
Bake
Bake in a quick oven at 400°F (200°C) for about 30 minutes or until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Baking soda
- Reacts with the acidity in the mixture to release gas, helping the cake rise.
- Butter
- Adds fat and richness, contributing to a tender crumb and flavour.
- Eggs
- Bind the batter and add structure and richness as they set.
- Brown sugar
- Adds sweetness, moisture and a deeper, molasses-like flavour.
The step that matters
Adding the baking soda to the dry ingredients. Baking soda needs an acidic partner to produce gas and lift the cake. It must be evenly mixed through the flour so it reacts uniformly; clumps can leave bitter spots or uneven rising.

Fit is the average pairing score against flour, butter, milk, caraway, raisin, sugar, egg. 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.
