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

What each ingredient does

Sugar
Sweetens the filling and helps it thicken into a creamy, spreadable texture as it cooks.
Butter
Adds fat for a rich mouthfeel and a smooth, creamy texture.
Fresh milk
Provides moisture and dissolves the sugar, forming the creamy base of the filling.
Almonds
Add crunch and nutty flavour that contrasts with the soft, creamy base.
Figs
Add chewy texture and natural sweetness to the fruit mixture.

The step that matters

Cook over medium heat until it begins to rope. Sugar syrup and milk must reach the right concentration to form a thread-like rope; overheating can scorch the sugars or make the filling too stiff, while underheating leaves it runny and unable to set when beaten and cooled.

Swap the currant

How well each one fits the dish's main ingredients (raisin, almond, fig, walnut, sugar, butter, milk):
