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 ↓
Fruit Tart
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
In a bowl, cream together the sugar and butter.
Add the molasses and eggs, mixing well.
Stir in the baking soda, raisins, currants, and flour until combined.
Fold in the sliced citron and spices.
Bake
Pour the mixture into a tart pan and bake for 30-40 minutes or until set.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Bind the batter and add structure as they set during baking.
- Butter
- Adds richness and tenderness through fat creamed with the sugar.
- Flour
- Provides the main structure that holds the tart together once baked.
- Baking soda
- Reacts with the molasses's acidity to lighten the batter and aid rising.
- Molasses
- Adds moisture, dark colour and a deep, sweet flavour.
- Raisins
- Add chewy texture and concentrated sweetness throughout the tart.
The step that matters
Stir in the baking soda. Baking soda needs an acid, such as the molasses here, to react and lighten the batter. Mixing it in evenly keeps the rise consistent and prevents dense or bitter pockets.
Swap the currant
How well each one fits the dish's main ingredients (sugar, butter, molasses, egg, raisin, flour):
- Vanillafits better
- Figfits better
- Datesfits about as well
- Currantthe original
Fit is the average pairing score against sugar, butter, molasses, egg, raisin, flour. Candidates are from the same food group and used in at least 100 recipes.
