Use the jam to fill our Peanut-Butter-Oat Drop Cookies, or mix it into yogurt, spread it on ricotta toast, or whisk into vinaigrettes. Ingredients 10 ounces frozen raspberries (2 ¼ cups) ⅓ cup sugar 1 teaspoon fresh lemon juice Pinch of kosher salt Directions In a medium saucepan, combine raspberries, sugar, lemon juice, and salt and bring to a boil over medium-high heat, stirring until sugar dissolves. Cook, stirring often and mashing berries with the back of a spoon, until mixture thickens to a jam-like consistency, 6 to 8 minutes. Strain through a sieve, if desired, then transfer to a heatproof jar and let cool completely. Refrigerate up to 1 week or freeze up to 3 months. Rate it Print
