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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Stale sponge cakes
- Absorb the sherry or syrup and give the dessert its structure.
- Cornflour
- Starch that thickens the boiled milk into a set custard.
- Arrowroot
- Second starch that adds thickening and a smooth, clear set.
- Milk
- Liquid base that the starches thicken into the custard.
- Red currant jelly
- Adds sweetness and a glossy finish to the top.
- Whipped cream
- Adds richness and a soft, light topping.
The step that matters
Cooking the custard until thickened. Starch granules only swell and thicken when heated in liquid. If the cornflour and arrowroot milk is not cooked long enough, the custard stays thin and will not set firmly once 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.
