Ingredients

Ingredients

  • 2 large lemons, washed and dried thoroughly
  • 1 cup water
  • 1 cup granulated sugar
  • 1 teaspoon vanilla extract (optional)

Instructions

  1. Prepare Lemons: Wash and dry lemons thoroughly using warm water to ensure all wax or residues are removed.
  2. Zest Lemons: Use a vegetable peeler or knife to remove the yellow zest carefully, avoiding any white pith, then slice the zest into thin strips.
  3. Segment and Chop Lemons: Peel the remaining lemons to remove all pith. Segment the lemon flesh, remove any seeds, and chop into small pieces for cooking.
  4. Simmer Lemons: In a saucepan, combine the lemon zest, chopped lemon flesh, and water. Bring the mixture to a boil, then reduce heat to simmer for 15 minutes to soften the fruit and infuse the water with lemon flavor.
  5. Add Sugar and Vanilla: Add the granulated sugar and vanilla extract if using. Stir well to dissolve the sugar, then continue to simmer the mixture for 30 to 40 minutes, stirring frequently to prevent sticking or burning.
  6. Check Jam Consistency: Skim off any foam that forms on the surface. Use the cold plate test by placing a small amount of jam on a cold plate and pushing it gently with a finger; if it wrinkles, the jam is ready.
  7. Jar the Jam: Carefully ladle the hot lemon jam into sterilized jars, seal them tightly, and allow to cool to room temperature before storing.

Notes

  • Using ripe, unwaxed lemons is preferred for best flavor and safety.
  • The vanilla extract is optional but adds a subtle aromatic depth to the jam.
  • Ensure jars are properly sterilized to safely preserve the jam.
  • The cold plate test is a reliable way to check jam readiness without a thermometer.
  • The jam thickens more as it cools.
  • Store sealed jars in the refrigerator and consume within a few weeks.
