Equipment
- Large saucepan or pot
- Sharp knife or mandoline
- Fine grater or zester
- Sterilized glass jars with lids
- Wooden spoon
Ingredients
- 4 large lemons (preferably organic, unwaxed)
- 2½ cups granulated sugar
- 2 cups water
- 1 tbsp lemon juice (for extra pectin and preservation)
Ingredient Notes
- Organic lemons: Essential, as you’ll be using the peel — avoid waxed lemons.
- Sugar: Balances the tartness and helps the jam set properly.
- Lemon juice: Natural preservative and thickener, enhancing the citrus flavor.
- Water: Helps soften the peel and extract flavor during boiling.
Instructions
Step 1: Prepare the Lemons
- Wash lemons thoroughly and scrub to remove any residue.
- Slice lemons thinly, removing seeds.
- Place slices in a bowl and cover with water. Let them soak for 4–6 hours (or overnight) to reduce bitterness.
Step 2: Cook the Lemons
- Drain soaked lemons and transfer them to a saucepan.
- Add 2 cups of water and bring to a boil.
- Reduce heat and simmer for about 20 minutes, until peels become tender.
Step 3: Add Sugar and Make the Jam
- Stir in the sugar and lemon juice.
- Cook over medium heat for 25–30 minutes, stirring occasionally.
- When the mixture thickens and coats the back of a spoon, it’s ready.
- (Optional: For a smoother texture, blend half of the jam and mix back in.)
Step 4: Store the Jam
- Pour hot jam into sterilized jars, leaving ½ inch of space at the top.
- Seal jars and invert for 10 minutes to create a vacuum seal.
- Allow to cool completely before storing in a cool, dark place.

Tips

- For extra shine, brush it over cakes or tarts as a natural glaze.
Variations
- Lemon & Ginger Jam: Add 1 tbsp finely grated fresh ginger for a spicy warmth.
- Honey Lemon Jam: Replace half the sugar with honey for a floral flavor.
- Citrus Mix: Combine lemons with oranges or grapefruits for a marmalade-style spread.
