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 ↓
Currant and Raspberry 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 a pastry with flour, butter, and water.
Roll out the pastry and line a tart pan.
Fill and bake
Mix currants, raspberries, and sugar in a bowl.
Pour the fruit mixture into the pastry shell.
Bake for 25-30 minutes until the crust is golden.
Serve
Let cool before serving.

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
- Flour
- Forms the structure of the pastry that holds the filling.
- Butter
- Adds fat that makes the pastry tender and helps it brown.
- Sugar
- Sweetens the fruit and helps it taste balanced against the tart berries.
- Currants
- Provide tart acidity and a bright flavour to the filling.
- Raspberries
- Add juiciness, aroma and sweet-tart flavour to the filling.
The step that matters
Let cool before serving. Fruit fillings thicken as they cool, and cutting the tart while hot can cause the juices to run and the filling to stay loose.
Swap the currant
How well each one fits the dish's main ingredients (sugar, butter, flour):

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