Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
2 cups whole milk
4 large egg yolks
1/2 cup granulated sugar
1/4 cup cornstarch
1 tablespoon lemon zest
1/4 cup limoncello liqueur
1 teaspoon vanilla extract
2 tablespoons unsalted butter
Directions
Start by heating the milk in a medium saucepan over medium heat. Add the lemon zest and allow the mixture to warm until it begins to steam, but do not let it boil.
In a separate bowl, whisk together the egg yolks and sugar until the mixture becomes pale and slightly thickened. Add the cornstarch and continue whisking until smooth and free of lumps.
Slowly pour the warm milk into the egg mixture while whisking constantly. This step tempers the eggs and prevents them from curdling. Once combined, return the mixture to the saucepan.
Cook over medium heat, whisking continuously, until the custard thickens. This usually takes about 5 to 7 minutes. The texture should become smooth and creamy, coating the back of a spoon.
Remove the saucepan from heat and stir in the limoncello, vanilla extract, and butter. Mix until the butter is fully melted and incorporated.
Transfer the custard to a bowl and cover with plastic wrap, pressing it directly onto the surface to prevent a skin from forming. Let it cool to room temperature, then refrigerate until fully chilled.

Variations
For a stronger citrus flavor, increase the lemon zest slightly or add a few drops of fresh lemon juice.
If you prefer a non-alcoholic version, substitute the limoncello with lemon juice and a bit of sugar syrup to maintain balance.
For a richer custard, replace part of the milk with heavy cream.
You can also fold in whipped cream once chilled to create a lighter, mousse-like texture.
Adding a pinch of turmeric can enhance the color naturally without affecting the flavor.
Storage/Reheating
Store the custard in an airtight container in the refrigerator for up to 3 days. Always keep plastic wrap pressed against the surface to avoid forming a skin.
This custard is best enjoyed cold or at room temperature. Reheating is not recommended, as it may affect the texture and cause separation. If it thickens too much after chilling, whisk it gently to restore its smooth consistency.
