Add the strawberries, water, and sugar to a medium sized saucepan over low heat.
Cook gently over low heat for 10-15 minutes, until the sugar is fully dissolved and the strawberries have infused the syrup with their color and flavor.
Let cool completely to room temperature, then strain into a glass jar and seal tightly with a lid.
Store the syrup in an airtight container in the fridge for up to a month.
Mojitos
Place basil leaves and strawberries into a sturdy glass. Use a muddler to gently crush the basil and strawberries to release the basil oils and juice.
Fill the glass halfway with ice. Pour the rum and simple syrup over the ice and then fill the glass with club soda.
Stir, taste, and add more simple syrup if desired. Garnish with basil and strawberries.
