Coulis is just a fancy word for a beautiful and versatile fruit sauce. You can serve it with ice cream, sorbet, pudding, chocolate cake, cheesecake, etc.
3 cups raspberries*
1/3 cup natural cane sugar
Pinch sea salt
Place all ingredients in a medium saucepan and bring to a boil over medium-high heat, stirring and mashing the berries. Reduce heat to medium and simmer for about 5 minutes, stirring frequently. Set a fine-mesh strainer over a bowl and strain the raspberry mixture, pressing on the solids with a wooden spoon or rubber spatula; discard the seeds. Or use a mouli food mill. Allow to cool.
*Frozen, thawed raspberries would work well.
