Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Barley
- Softens and releases starch, giving the cream its body and a grainy texture.
- Eggs
- Their proteins set as they heat, thickening and enriching the cream.
- Arrowroot
- A starch that thickens the mixture when heated, giving a smooth, glossy texture.
- Milk
- Provides liquid and creaminess, forming the base of the dish.
- Sugar
- Adds sweetness and balances the richness of the cream.
- Brandy
- Adds aroma and a warm flavour to the finished cream.
The step that matters
Stirring the egg mixture into the boiling cream. Egg proteins set at high heat and can curdle or scramble if added too quickly. Stir constantly while pouring, and remove from heat as soon as the mixture thickens.
