1. Preparing the Oil-Based Pastry
In a bowl, whisk the egg, sugar, and lemon zest. Pour in the sunflower oil and mix well. Sift in the flour and baking powder. Knead briefly until a smooth dough forms. Pro Tip: Oil-based doughs do not need to rest like butter doughs; you can roll them out immediately.
2. Shaping and Baking the Shells
Press the dough into mini tartlet molds, ensuring the edges are even. Prick the bottoms with a fork to prevent air bubbles. Bake in a preheated oven at 180°C (350°F) for 12–15 minutes or until they reach a pale golden color. Let them cool completely.
3. The Lemon Cream Custard
In a saucepan, whisk the egg yolk, sugar, and cornstarch. Slowly pour in the milk while whisking to avoid lumps. Cook over medium heat, stirring constantly, until the mixture thickens into a heavy cream consistency.
4. The Flavor Finish
Remove from heat and immediately stir in the vanilla extract and the fresh lemon juice. Stirring the juice in at the end preserves the bright, fresh enzymes of the lemon that would otherwise be dulled by boiling.
5. Assembly
Spoon the warm lemon cream into the cooled tartlet shells. Smooth the tops and allow them to set at room temperature for 30 minutes, then refrigerate for at least 1 hour.
Serving and Storage: The Final Touch
Serving: Garnish with a thin slice of lemon, a dusting of powdered sugar, or a single fresh raspberry for a professional look.

Tips: Grandma’s Secrets for Success
- Zest First: Always zest your lemon directly into the sugar. Rub the zest and sugar together with your fingers to release the essential oils before adding the other ingredients.
- The Cornstarch Slurry: If you are worried about lumps, mix the cornstarch with a small amount of cold milk before adding it to the egg yolk and sugar.
- Don’t Overbake: These tartlets should be light gold. Overbaking oil-based pastry can make it overly hard rather than crisp.
Variations: Twists on the Classic
- The Meringue Top: Use the leftover egg white from the cream recipe to make a quick meringue topping for a “Lemon Meringue” style tartlet.
- White Chocolate Bottom: Brush the inside of the cooled shells with melted white chocolate before adding the cream; this prevents the crust from getting soft and adds a sweet snap.
Conclusion: A Taste of Home
Grandma’s Lemon Tartlets are a reminder that the best desserts are those made with intention and fresh ingredients. The combination of the crisp, lemon-scented shell and the velvety, citrusy cream creates a “mouthwatering” experience that feels both elegant and deeply personal. It’s a recipe that has lasted for generations because it simply works every time.
Frequently Asked Questions:
Q: Can I use butter instead of sunflower oil?
A: Yes, use 100g of softened butter, but you will need to chill the dough for 30 minutes before baking.
Q: Why did my cream not thicken?
A: You likely didn’t bring the mixture to a high enough temperature. Cornstarch requires the liquid to reach a gentle bubble to activate its thickening properties.
Q: Can I make the shells in advance?
A: Absolutely! The baked shells will stay crisp in an airtight container for up to 5 days. Fill them the day you plan to serve them.
