Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich the custard and help it set as it thickens.
- Cornstarch
- Starch swells when heated, thickening the custard into a smooth filling.
- Sugar
- Adds sweetness and helps give the custard its body.
- Butter
- Adds fat for richness and a smoother, silkier mouthfeel.
- Grated pineapple
- Adds fruity flavour, acidity and moisture to the filling.
The step that matters
Stirring in the beaten egg yolks off the heat. Egg proteins set at higher temperatures and can scramble if added to a very hot mixture. Removing the pan from the heat first and stirring steadily helps the yolks thicken the custard smoothly instead of curdling.
