Store
Store in a covered jar; it will keep for months.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks and whites thicken the filling as it cools and give it a rich, set body.
- Lemon juice
- Provides the sharp acidity that balances the sweetness and gives the filling its flavour.
- Butter
- Adds fat that gives the filling a smooth, rich texture.
- Sugar
- Sweetens the filling and helps it thicken when heated with the butter.
The step that matters
Stirring over medium heat. Stirring constantly keeps the butter, sugar and heat evenly distributed so the mixture thickens smoothly without scorching or lumping. Pulling it from heat at the honey-like stage keeps it from becoming grainy.
