Ingredients

  • 2 lbs fresh strawberries, hulled
  • 1 ½ cups organic cane sugar
  • ¼ cup lemon juice
  • pinch of sea salt

Instructions

  • Heat large saucepan over medium-low heat and add strawberries, sugar and lemon juice. Stir until sugar is dissolved.
  • Increase saucepan to medium-high to bring mixture to a boil. Continue to boil for 15 minutes or until thickened. If you have a candy thermometer, just boil until the temperature reaches 220°F. Remove from heat and add pinch of salt.
  • Transfer the jam to a jar and let cool at room temperature. Store in fridge and use within 1 month.
  • If you want to keep for longer remove from the stove & immediately ladle into sterilized jars. Place lids on jars and screw on. Place in boiling water with at least 1 inch covering the jars for 10 minutes to seal the jars. Remove and let sit at room temperature for 1 day. Store in cool dark place. Once opened, you need to store in fridge and use within 1 month.

Notes

  • Using undamaged fruit is important as the jam will likely deteriorate quickly.
  • Use as fresh of strawberries as possible. I make my jam when strawberries are in season. Good thing is jam will last for 2 years if sealed properly.
  • While granulated sugar is fine, high quality cane sugar is better for this jam recipe as it helps low-pectin fruits like strawberries set.
  • Speaking of low-pectic fruits, lemon juice is also super important with helping the strawberries create a jam-like consistency.
  • Always use clean, sterilized jars. If they aren't clean, bacteria will build up and all your hard work will be for not.
  • Use the cold plate test mentioned above to make sure the jam is ready. If the jam wrinkles up after you push it with your finger, it is ready.
