In a medium saucepan, bring strawberries, sugar, 3 tablespoons water, and salt to a boil over medium heat. Reduce heat, and simmer until strawberries are just tender, about 12 minutes. Remove from heat, and let cool completely. Stir in lemon juice.
Strain mixture through a fine-mesh sieve into a small bowl, gently pressing solids with a spatula to extract as much liquid as possible. Cover and refrigerate for up to 1 week.
