Ingredients
- 8–10 large organic lemons
- 700 g (3½ cups) granulated sugar
- 500 ml (2 cups) freshly squeezed lemon juice
- Optional: 1 teaspoon citric acid (helps preserve freshness)
- Optional: 1 teaspoon vanilla extract for a softer flavor
Equipment
- Large glass jar with lid
- Vegetable peeler
- Fine mesh strainer
- Cheesecloth (optional)
- Large bowl
- Funnel
- Sterilized glass bottles
Step 1: Choose the Right Lemons
The quality of your lemons determines the quality of the syrup.
Choose lemons that are:
- Bright yellow
- Firm
- Heavy for their size
- Fragrant
- Preferably organic since you’ll use the peel
Avoid lemons with soft spots or thick blemishes.
Step 2: Wash the Lemons
Wash each lemon thoroughly using warm water.
Scrub the peel gently with a vegetable brush to remove dirt or wax.
Dry completely using clean kitchen towels.
Step 3: Peel the Lemons
Using a vegetable peeler, remove only the yellow outer peel.
Avoid removing too much of the white pith, which tastes bitter.
Place all peels into the clean glass jar.
Step 4: Add the Sugar
Pour all of the sugar over the lemon peels.
The sugar should completely surround the peels.
Seal the jar tightly.
Step 5: Macerate
Shake the jar gently.
Leave it at room temperature.
Shake it several times every day.
After 24 hours the sugar will begin melting.
After 48 hours even more liquid will appear.
Within 3–5 days almost all of the sugar should dissolve.
The sugar slowly extracts the aromatic oils from the peel, producing a wonderfully fragrant syrup.
Step 6: Juice the Lemons
Once you’ve removed the peel, squeeze all of the lemons.
Remove seeds.
You should obtain approximately 500 ml (2 cups) of fresh juice.
Keep refrigerated until the peel syrup is ready.
Step 7: Combine
When the sugar has completely dissolved, pour the fresh lemon juice into the jar.
Mix well.
If using citric acid, stir it in now.
Seal again.
Allow everything to infuse another 24 hours.
Step 8: Strain
Pour the mixture through a fine mesh strainer.
For an extra-clear syrup, strain again through cheesecloth.
Press the peels gently to extract every drop of flavorful syrup.
Do not squeeze too aggressively or bitterness may be released.
Step 9: Bottle
Using a funnel, pour the syrup into sterilized bottles.
Seal tightly.
Refrigerate immediately.

Why This Method Works
The secret lies in osmotic extraction. Sugar naturally draws moisture and aromatic oils from the lemon peel without applying heat. Since the peel contains highly concentrated essential oils, the resulting syrup develops an intense citrus aroma that cannot be achieved by simply mixing lemon juice and sugar.
Adding the fresh juice after the sugar has extracted the peel oils creates a balanced syrup with bright acidity, fragrant zest notes, and a smooth sweetness. Because the syrup isn’t boiled, it retains more of the lemons’ fresh flavor and delicate aroma.
