These biscotti are loaded with lilac flavour and scent. Lilac petals are incorporated into the biscotti dough which has been sweetened with homemade lilac sugar. Glazed and topped with more lilacs, these Lilac Blossom Biscotti are light, airy, and delicious! Super easy to make, and with their cheerful inclination, no one could resist! Treat yourself to one of these with a hot tea on a lazy Sunday afternoon.
