In a medium saucepan, combine strawberries, sugar, water, and lemon juice.

Heat the mixture on medium-high until it boils, stirring occasionally until the sugar is fully dissolved.

Reduce heat to medium-low and simmer for 15-20 minutes, until strawberries are soft and the syrup thickens.

Remove from heat and let it cool slightly.

Pour the mixture through a fine mesh sieve into a clean container, gently pressing to extract the syrup. Discard the solids.

Let the syrup cool completely before storing it in the refrigerator.
