Dissolve the Cornstarch
In another bowl, mix the cornstarch with 1 tablespoon of cold milk until smooth. This will help prevent lumps from forming in your custard.
Temper the Eggs
Slowly pour a bit of the warm milk into the egg mixture while whisking constantly. Gradually add the remaining milk, ensuring that the eggs do not scramble.
Cook the Custard
Return the combined mixture to the saucepan and cook over low heat. Stir constantly until the mixture thickens to a custard-like texture.
Add Lemon and Condensed Milk
Once thickened, stir in the lemon juice and sweetened condensed milk until fully combined. This will enhance the custard’s creamy consistency and tangy flavor.
