Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the mixture as their proteins set with gentle heat, giving a creamy body.
- Butter
- Adds fat for richness and a smooth, silky texture.
- Lemon juice
- Provides acidity and bright lemon flavor that balances the sugar.
- Loaf sugar
- Sweetens the mixture and dissolves into the liquid to give a smooth result.
- Lemon rind
- Rubbing sugar on the rind draws out aromatic lemon oils into the sugar.
The step that matters
Keep the heat low once the yolks go in. Egg yolks thicken as their proteins set with gentle heat, but too much heat scrambles them into lumps. Stir constantly and stop as soon as the mixture begins to boil.
