Ingredients
Method
Preparation
- In a small saucepan, mix together water and cornstarch thoroughly.
- Ensure no lumps remain and that you achieve a smooth mixture.
- When the cornstarch dissolves, add the granulated sugar, lemon juice, and a slightly beaten egg.
- Incorporate these ingredients slowly while stirring to maintain a consistent texture.
Cooking
- Cook over medium heat, stirring constantly until it thickens and comes to a boil (about 5–7 minutes).
- You’ll notice the filling becoming glossy and more substantial.
- If adding food coloring, incorporate it during this step, stirring gently.
- Remove the thickened lemon mixture from the heat and let it cool slightly before using.
- Allow the filling to cool completely before covering and storing it in the refrigerator (it can be used within a week).
Notes
For lower-sugar options, consider a sugar alternative that can withstand heat. Fresh lemons can be used instead of concentrated lemon juice for a zestier flavor. Avoid skipping the stirring process to prevent lumps, and allow the filling to cool thoroughly for best results.
