Why it works: Pistachio and raisin share more aroma than cooks usually use. They rank in the top 9% of all ingredient pairs, and cooks put them together in 63 recipes. Both carry alpha-terpineol, which smells lilac, floral. The science ↓
Sultana Roll and Claret Sauce
Ingredients
Directions
Prepare the raisins
Boil sultana raisins for 5 minutes.
Soak the boiled raisins in brandy for several hours.
Drain the raisins before using.
Assemble the roll
Line a one-pound baking powder can with pistachio ice cream.
Sprinkle the drained raisins inside the can.
Fill the center with sweetened and flavored whipped cream.
Cover the top with more pistachio ice cream.
Pack the can in ice and salt for 2 hours before serving.
Make the claret sauce
Boil sugar and water until thick syrup forms.
Let the syrup cool slightly.
Add claret to the syrup.
Serve the claret sauce very cold over the sultana roll.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sultana raisins
- Soaked in brandy, they add chewy texture and concentrated fruit flavor to the filling.
- Whipped cream
- Adds a light, airy texture and moisture to the center of the frozen roll.
- Pistachio ice cream
- Forms the frozen outer shell and provides the main flavor and creamy body.
- Sugar
- Dissolves in water to make a syrup that sweetens and thickens the claret sauce.
- Claret
- Adds acidity and wine flavor to the syrup, making the sauce tangy and aromatic.
The step that matters
Packing the can in ice and salt. Salt lowers the melting point of the ice, so the mixture gets colder than ice alone. This keeps the ice cream firm while the roll sets; without enough cold, it softens and loses its shape.
Swap the pistachio
How well each one fits the dish's main ingredients (cream, raisin, brandy, sugar):
- Almondfits better
- Chestnutfits better
- Pistachiothe original
- Brazil nutfits less well
Fit is the average pairing score against cream, raisin, brandy, sugar. Candidates are from the same food group and used in at least 100 recipes.
