This homemade strawberry jam is fresh, sweet, and perfect for spreading on toast or adding to your desserts. It's incredibly easy to make and requires only a few simple ingredients.
In a large bowl, combine strawberries and sugar. Let sit for 10 minutes, stirring occasionally to allow the strawberries to release their juices.
Transfer the strawberry mixture to a heavy-bottomed saucepan. Add the lemon juice and lemon zest if using.
Cook over medium heat, stirring constantly, until the mixture reaches a boil. Reduce heat and simmer for 20 minutes or until thickened, stirring occasionally.
Remove from heat and let cool. Pour the jam into sterilized jars and seal tightly.
Notes
Store the jam in the refrigerator for up to two weeks. For long-term storage, process in a hot water bath and keep in a cool, dark place.
