In this recipe I used fresh chopped rose petals. You can also add a splash of rose water for a light floral taste that goes well with the nutty cashew flavor. For a slightly more fragrant kaju barfi, add a few threads of saffron while forming the dough. Try cardamom cashew fudge by adding a dash of ground cardamom seeds to the dough. Or use a bit of vanilla extract for an even more indulgent dessert.
