Lemon Thumbprints Recipe

Unsalted butter: Provides a rich, creamy base for the cookies and the lemon curd.

Granulated sugar: Adds sweetness to both the cookie dough and the lemon curd.

Egg yolks: Contributes to the structure and richness of the cookies and the curd.

Vanilla extract: Enhances the flavor of the cookies with a subtle, sweet aroma.

All-purpose flour: Forms the base of the cookie dough, giving it structure and texture.

Salt: Balances the sweetness and enhances the overall flavor of the cookies.

Lemon juice: Provides a fresh, tangy flavor for the lemon curd.

Lemon zest: Adds a concentrated citrus flavor and aroma to the lemon curd.

When making the lemon curd, ensure you cook it over medium heat and stir constantly to prevent the egg yolks from curdling. If the mixture starts to thicken too quickly or unevenly, you can reduce the heat slightly. Once the curd has thickened, immediately remove it from the heat and stir in the butter until it melts completely, creating a smooth and glossy finish. This will give your lemon thumbprints a rich and velvety texture.

• unsalted butter - Substitute with coconut oil: Provides a dairy-free alternative with a slight coconut flavor.

• To keep your lemon thumbprints fresh, store them in an airtight container at room temperature. They will stay delicious for up to 3-4 days.
• If you prefer to refrigerate, place the cookies in a single layer in an airtight container. This will extend their freshness to about a week.
• For longer storage, you can freeze the lemon thumbprints. Arrange them in a single layer on a baking sheet and freeze until solid. Once frozen, transfer them to a freezer-safe bag or container. They can be frozen for up to 2 months.
• When ready to enjoy, thaw the cookies at room temperature for about an hour. If you prefer a warm treat, you can reheat them in a preheated oven at 300°F (150°C) for 5-7 minutes.
• To prevent the lemon curd from becoming too soft or runny during storage, you can refrigerate the curd separately and fill the cookies just before serving.
• If you have leftover lemon curd, store it in an airtight container in the refrigerator for up to a week. It can also be frozen in a freezer-safe container for up to 2 months.

• Preheat your oven to 300°F (150°C). Place the lemon thumbprints on a baking sheet lined with parchment paper. Warm them for about 5-7 minutes, or until they are heated through. This method helps maintain their delightful texture.

• Use a microwave for a quick reheat. Place a few cookies on a microwave-safe plate and heat them on medium power for 10-15 seconds. Be cautious not to overheat, as this can make the lemon curd too runny.

• For a toaster oven, set it to 300°F (150°C) and place the lemon thumbprints on the rack or a small baking tray. Heat for 5-7 minutes, ensuring they are evenly warmed without becoming too crispy.

• If you prefer a stovetop method, use a double boiler. Place the cookies on a heatproof plate and set it over simmering water for a few minutes. This gentle heat will warm the lemon curd without drying out the cookie base.

• For an air fryer, preheat it to 300°F (150°C). Place the lemon thumbprints in the basket in a single layer and heat for 3-5 minutes. This method ensures a quick and even reheat while preserving the cookie's texture.
