Why it works: Arrowroot 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 16 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Prince of Wales Dessert
Ingredients
Directions
Prepare the mold
Dip stale sponge cakes in sherry or syrup and line a mold with them.
Soak the cakes in raspberry juice or wine.
Make the custard
Mix cornflour and arrowroot together, then add boiling milk and cook for a few minutes.
Stir in vanilla and pour the mixture into the lined mold.
Assemble and serve
Once cold, turn out the dessert onto a serving plate.
Top with a large spoonful of red currant jelly and sprinkle with chopped pistachio nuts.
Layer the soaked cakes as above.
Spread whipped cream on top, and decorate with cherries and chopped citron peel if desired.
Serve very cold in the glass dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cornflour
- Thickens the milk into a set, sliceable custard that holds the dessert's shape.
- Arrowroot
- Adds extra thickening power, giving the custard a smooth, glossy set.
- Sponge cakes
- Form the soft, absorbent base layers that take up the sherry or syrup.
- Milk
- Forms the liquid base that the starches thicken into custard.
- Red currant jelly
- Adds sweetness and a tart fruit glaze over the top layer.
The step that matters
Cooking the cornflour and arrowroot mixture. Starch must be cooked with the boiling milk for a few minutes so the granules swell and gelatinize; undercooked starch stays chalky and fails to set firmly when cold.
Swap the raspberry
The recipe marks raspberry as optional. How well each one fits the dish's main ingredients (sherry, arrowroot, milk, vanilla, red currant, pistachio, nuts):
- Figfits about as well
- Cherryfits about as well
- Raspberrythe original
- Coconutfits about as well
Fit is the average pairing score against sherry, arrowroot, milk, vanilla, red currant, pistachio, nuts. Candidates are from the same food group and used in at least 100 recipes.
