Homemade Strawberry Jam Recipe

4.5 from 62 reviews

This classic homemade strawberry jam recipe uses fresh strawberries, sugar, and lemon juice to create a sweet and tangy preserve perfect for spreading on toast or adding to desserts. Optional pectin can be added for a thicker consistency. The jam is cooked on the stovetop and preserved through a boiling water bath method for safe storage.

Ingredients

Scale

Strawberries

  • 2 pounds fresh strawberries (hulled and sliced)

Others

  • 4 cups granulated sugar
  • 1 lemon juice (freshly squeezed)
  • 1 package pectin (optional, for thicker jam)

Instructions

  1. Prepare the Strawberries: Wash and hull the strawberries, then slice them into small pieces to ensure even cooking and to help the jam set properly.
  2. Combine Ingredients: In a large pot, combine the sliced strawberries, sugar, and freshly squeezed lemon juice. Stir well to evenly distribute the sugar.
  3. Cook the Jam: Heat the mixture over medium heat, stirring frequently until the sugar dissolves completely. This prevents burning and promotes even cooking.
  4. Boil and Thicken: Bring the mixture to a boil and continue cooking for 20-30 minutes, stirring occasionally, until the jam reaches the desired thick consistency. If using pectin, add it now following the package instructions to help the jam set.
  5. Jar the Jam: Remove the pot from the heat and carefully ladle the hot jam into sterilized jars, leaving about 1/4 inch of headspace to allow for expansion.
  6. Seal and Process: Seal the jars with lids and process them in a boiling water bath for 10 minutes. This step ensures long-term preservation and food safety.

Notes

  • The lemon juice not only adds flavor but also helps to balance the sweetness and aids the jam’s natural pectin in setting.
  • Using pectin is optional but recommended if you prefer a firmer jam.
  • Ensure jars are properly sterilized to prevent contamination and spoilage.
  • Store sealed jars in a cool, dark place. Refrigerate after opening.
  • If you prefer chunkier jam, slice strawberries thicker or mash fewer pieces.
