You can store this strawberry coulis in the refrigerator in an air-tight container for up to a week, or store in the freezer in a freezer safe container for up to 3 months. For easy portioning, you can also pour the strawberry coulis into an ice cube mold and freeze until solid. Then transfer the strawberry sauce cubes to a freezer safe bag or container. Remove as many cubes as you would like to use and heat in a pan on the stovetop until smooth before serving.
