This guide shows you how to turn a bag of lemons into three pantry staples: lemon curd, lemon salt, and lemon extract. Each recipe is designed to be made in under 30 minutes of active time, with precise temperatures and times to ensure consistent results.

Whether you're a seasoned cook or a beginner, these recipes are straightforward and foolproof if you follow the exact steps.
Why You'll Love This Recipe
About the Ingredients
6 large lemons (about 2 lbs / 900g) – organic if possible
Organic lemons are best because you'll use the zest and peel. If not organic, scrub well with a vegetable brush to remove wax and pesticides.
1 cup (200g) granulated sugar
For the lemon curd. You can substitute with honey, but it will change the flavor and consistency slightly.
3 large eggs
For the lemon curd. Use fresh, room-temperature eggs for smoother curd.
1/2 cup (115g) unsalted butter, cut into small cubes
Use good-quality butter for the best flavor. Salted butter works too, but reduce added salt if using.
1/2 cup (120ml) fresh lemon juice (from about 3-4 lemons)
Strain the juice to remove seeds and pulp for a smoother curd.
1 tablespoon (15g) lemon zest (from about 2 lemons)
Zest before juicing. Use a microplane for fine zest.
1/2 cup (120g) coarse sea salt or kosher salt
For the lemon salt. Use a coarse salt that doesn't contain iodine, as it can cause a bitter taste.
1 cup (240ml) vodka or grain alcohol (80-100 proof)
For the lemon extract. Use a neutral spirit; vodka is most common. Avoid rum or whiskey as they add unwanted flavors.
1 cup (240ml) water (for lemon salt, if using)
Optional: Used to dissolve salt and zest before drying, if you prefer a more integrated salt.
Tips & Tricks
- Always zest lemons before juicing—it's easier and you'll get more zest.
- When making lemon curd, stir constantly over low heat to prevent curdling; use a thermometer to hit 170°F (77°C).
- For lemon salt, dry it thoroughly in a low oven (200°F/93°C) for 2-3 hours to prevent clumping.
- Label your lemon extract with the date; it needs at least 4-6 weeks to develop full flavor.
Pro Tips
Step-by-Step Instructions
1. Prepare Lemons
Wash and dry the lemons. Zest 3 lemons (about 1.5 tablespoons) for the curd and 2 lemons for the salt (about 1 tablespoon). Then juice 4 lemons to get 1/2 cup of juice. For the extract, peel 1 lemon with a vegetable peeler, avoiding the white pith.
2. Make Lemon Curd
In a heatproof bowl, whisk together sugar, eggs, lemon juice, and lemon zest. Place the bowl over a saucepan of simmering water (double boiler). Cook over medium-low heat, stirring constantly with a whisk, until the mixture thickens and reaches 170°F (77°C) on an instant-read thermometer. This should take about 10 minutes. The curd should coat the back of a spoon.
3. Finish Curd
Remove the bowl from heat and whisk in the butter cubes one at a time until melted and smooth. Strain through a fine-mesh sieve into a clean jar. Let cool to room temperature, then refrigerate. The curd will thicken further as it cools.
4. Make Lemon Salt
Preheat oven to 200°F (93°C). In a small bowl, combine coarse salt and lemon zest. Rub the zest into the salt with your fingers until well distributed. Spread the mixture on a parchment-lined baking sheet. Bake for 2-3 hours, stirring every 30 minutes, until the salt is completely dry and no longer clumps. Let cool and store in an airtight jar.
5. Make Lemon Extract
Use a vegetable peeler to remove the peel from 1 lemon, avoiding the white pith. Place the peel in a clean glass jar. Pour the vodka over the peel, making sure it's completely submerged. Seal the jar and store in a cool, dark place for 4-6 weeks, shaking gently once a week. After 6 weeks, strain out the peel and transfer the extract to a dropper bottle.
6. Store and Label
Label each jar with the date and contents. Lemon curd will keep in the refrigerator for up to 2 weeks. Lemon salt can be stored at room temperature indefinitely if kept dry. Lemon extract will keep indefinitely in a cool, dark place.
Delicious Variations
Spiced Lemon Curd
Add 1/2 teaspoon ground ginger and 1/4 teaspoon cinnamon to the curd before cooking.
Herbed Lemon Salt
Mix in 1 tablespoon dried thyme or rosemary with the salt and zest before drying.
Vanilla-Lemon Extract
Add 1 vanilla bean (split) to the jar with the lemon peel for a vanilla-lemon flavor.
How to Store DIY Lemon Recipes
Refrigerator
Lemon curd: store in an airtight jar in the fridge for up to 2 weeks. Lemon salt: store in an airtight container at room temperature, but if you live in a humid climate, keep it in the fridge to prevent clumping.
Freezer
Lemon curd can be frozen for up to 3 months in a freezer-safe container. Thaw in the fridge overnight. Lemon salt and extract do not need freezing.
Reheating
Lemon curd: serve cold or at room temperature. If you want it warm, heat gently in a saucepan over low heat, stirring constantly, until just warm. Do not microwave as it can curdle.
Frequently Asked Questions
Q: How long does homemade lemon curd last in the fridge?
Homemade lemon curd lasts up to 2 weeks in the refrigerator when stored in an airtight container. Because it contains eggs and butter, it's perishable, so always check for off-odors or mold before using.
Q: Can I use bottled lemon juice instead of fresh?
No, you should use fresh lemon juice for the best flavor. Bottled juice often contains preservatives and lacks the bright, fresh taste of fresh lemons, which is essential for a good curd and extract.
Q: What can I use lemon salt for?
Lemon salt is a versatile seasoning that adds a citrusy kick to roasted vegetables, grilled fish, salads, and even rimmed glasses for cocktails. Use it as a finishing salt, not for cooking, to preserve the lemon flavor.
Q: How long does it take to make lemon extract?
Lemon extract requires 4-6 weeks of steeping time to develop full flavor. While you can use it after 2 weeks, the flavor will be weaker. Patience yields a more robust extract.
Q: Can I use lemon extract in baking?
Yes, lemon extract is perfect for baking. Use it in cakes, cookies, and frostings. Substitute 1 teaspoon of lemon extract for 1 tablespoon of lemon zest or juice in recipes.
