In a saucepan, combine the sliced strawberries, sugar, and water.

Bring the mixture to a boil over medium heat, stirring occasionally.

Once boiling, reduce the heat and let it simmer for about 10-15 minutes, or until the strawberries are soft and the syrup thickens.

Remove from heat and stir in the lemon juice.

Using a strainer, strain the syrup into a clean container to remove the strawberry solids.

Let it cool before using or storing.
