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

What each ingredient does

Vinegar
Provides the sharp, tangy flavour that defines the filling.
Egg yolks
Thicken the filling and add richness as they set with heat.
Flour
Stabilises the custard-style filling so it sets smoothly rather than runny.
Sugar
Balances the acidity of the vinegar and adds sweetness to the filling and topping.
Butter
Adds fat for richness and a smoother mouthfeel in the filling.
Egg whites
Whipped to stiff peaks to form a light meringue topping that browns in the oven.

The step that matters

Stirring the egg and flour mixture into the boiling vinegar mixture. Egg yolks and flour must be stirred in while the liquid is boiling and cooked until well combined; adding them to a cooler liquid or not stirring well can leave lumps or a thin, unset filling, since the yolks thicken only when heated and the flour needs heat to gelatinise.
