If possible, use seedless jam, which won't require the straining in the first step. Ingredients 1 jar (12 ounces) blackberry jam (not jelly) 1 cup heavy cream 1 tablespoon confectioners' sugar ½ cup mixed fresh berries Directions Pass jam through a fine sieve; discard solids. With a mixer fitted with the whisk attachment, beat cream and sugar until soft peaks form. Gently fold jam into cream to form swirls.
