  7. Flavor with 2 tablespoons of orange‑flower or rose water.

  8. Strain through a coarse sieve, stirring until nearly cold.

Set and serve

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Thin cream
Provides the rich base and fat that give the custard its smooth, creamy texture.
Isinglass
A gelatin-like setting agent that firms the cream into a sliceable, wobbly custard as it cools.
Ground rice
Starch that thickens the mixture and helps give it a smooth body.
Bitter almonds
Adds a distinctive almond aroma and flavor to the cream.
Orange-flower or rose water
Adds a floral aroma that perfumes the custard.

The step that matters

Adding the cold cream and rice mixture to the hot cream. Stirring constantly while pouring prevents the starch from clumping and lumps from forming, so the custard thickens evenly and stays smooth.

Swap the orange

  4. Orangethe original

Fit is the average pairing score against cream, almond, rice, cucumber. Candidates are from the same food group and used in at least 100 recipes.
