Why it works: Biscuit and pistachio share more aroma than cooks usually use. They rank in the top 1% of all ingredient pairs, and cooks put them together in 53 recipes. Both carry nonanal, which smells fat, citrus. The science ↓
Ratafia Cream Basket
Ingredients
Directions
Prepare the base
Cut a round or oval piece of sponge cake, about 4 inches long and 2 inches wide.
In a saucepan, combine sugar, 2 tablespoons of water, and cream of tartar.
Boil gently until it reaches 300°F (150°C) or turns pale yellow.
Place the saucepan in a pan of boiling water.
Build the basket
Dip each ratafia biscuit in the sugar.
Stick the dipped biscuits around the edge of the sponge cake.
Add a second row of biscuits on top.
Add a third row of biscuits on top.
Dip each biscuit in sugar to hold them together.
Shape the basket as you go.
Pipe royal icing around the top edge of the basket.
Sprinkle the basket with chopped pistachio nuts.
Fill and serve
Whip the trifle cream.
Fill the basket with the whipped trifle cream just before serving.
Create a handle using a thin strip of angelica soaked in warm water to make it bend.
Sprinkle the cream with pistachio nuts.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ratafia biscuits
- Form the crisp walls of the basket, held together by the sugar coating.
- Sugar
- Forms a syrup that coats and binds the biscuits together as it cools and hardens.
- Cream of tartar
- Acidity that helps keep the boiled sugar syrup from crystallising.
- Trifle cream
- Provides the moist, creamy filling for the basket.
The step that matters
Boiling the sugar to 300°F (150°C). Sugar that is boiled too little stays soft and will not bind the biscuits, while overcooked sugar turns dark and bitter. Hitting the hard-crack stage gives a glassy coating that sets firm as it cools.
Swap the angelica
How well each one fits the dish's main ingredients (biscuit, sugar, cream, pistachio, nuts):
- Nutmegfits better
- Capersfits about as well
- Cinnamonfits about as well
- Angelicathe original
Fit is the average pairing score against biscuit, sugar, cream, pistachio, nuts. Candidates are from the same food group and used in at least 100 recipes.
