Servings & Timing
- Servings: 2–4
- Prep Time: 5 minutes
- Cook Time: 6–8 minutes
- Chill Time: 1–2 hours
- Total Time: 10 minutes + chilling
Ingredients List
- 400 ml (13.5 fl oz) whole milk (or dairy-free alternative)
- Zest of 1 lemon (preferably organic)
-
1 teaspoon vanilla sugar
or ½ teaspoon vanilla extract + 1 teaspoon sugar - 2 egg yolks
- 40 g (1.4 oz) sugar (or sugar substitute for a lower-carb option)
- 15 g (0.5 oz) cornstarch
Instructions
1. Prepare the Milk Base
Add the whole milk to a saucepan.
Stir in the lemon zest and vanilla sugar (or vanilla extract + sugar).
Heat gently over medium heat until warm, but not boiling.
2. Make the Egg Mixture
In a bowl, whisk together:
- egg yolks
- sugar
- cornstarch
Whisk until smooth and slightly pale.
3. Temper the Egg Mixture
Slowly pour a small amount of the warm milk into the egg mixture while whisking continuously.
This prevents curdling and ensures a silky custard.
4. Combine and Cook
Pour the tempered mixture back into the saucepan.
Cook over medium heat, whisking constantly, until the custard thickens—about 5–7 minutes.
The custard is ready when:
- it coats the back of a spoon
- lines stay when you run your finger through it
Do not boil.
5. Remove From Heat
Take the pan off the heat.
Strain the custard through a fine mesh sieve into a bowl for an ultra-smooth texture (optional but recommended).
6. Chill
Pour into dessert glasses or a container.
Place plastic wrap directly on top of the custard to prevent a skin from forming.
Refrigerate for 1–2 hours until cold and set.
7. Serve
Enjoy as-is or top with:
- fresh berries
- whipped cream
- crushed cookies
- lemon zest
- toasted coconut
Additional Notes
- For a stronger lemon flavor, add 1 teaspoon lemon juice after removing from heat.
- For thicker custard, increase cornstarch to 20 g.
- For dairy-free, use almond milk or oat milk, but the texture will be slightly lighter.

FAQs
Why is my custard lumpy?
It cooked too fast. Strain it, and next time use medium heat and whisk constantly.
Can I make this without egg yolks?
Yes. Increase cornstarch to 25 g. Texture will be lighter but still thick and creamy.
Why didn’t my custard thicken?
It may need an extra 1–2 minutes of cooking, or more cornstarch if using a dairy-free milk.
Can I double the recipe?
Yes. Cooking time increases slightly but technique stays the same.
