Don't let summer go by without making this strawberry sauce. It's a key component in our Strawberry Shortcake Sundaes.
Stir together berries, sugar, salt, and lemon juice in a saucepan. Bring to a boil, mashing with a potato masher and stirring frequently. Cook at a low boil, stirring more frequently as mixture thickens, until sauce clings to a spoon, about 10 minutes. Skim foam from top. Let cool completely.
