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

What each ingredient does

Arrowroot
Thickens the liquid as it heats, giving the dessert its firm, smooth set.
Eggs
Add richness and body, helping the mixture set firmly.
Butter or cream
Adds fat, which gives a silky texture and a softer mouthfeel.
Milk
Forms the main liquid base and adds creaminess to the set dessert.
Bitter almonds
Provide the characteristic almond aroma and flavour.

The step that matters

Boil the milk and stir it into the mixture until thick. Arrowroot thickens only when it is heated, so the mixture must get hot. Constant stirring keeps the starch and beaten eggs from clumping or scrambling, which gives a smooth, even set.

Swap the orange
