How can you make a delicious risotto even more delicious? Make the leftovers into arancini. Arancini are delicious fried balls of risotto, often stuffed with cheese and served with tomato sauce. I made them tonight with a delicata squash risotto that I took to the Thanksgiving dinner that my husband I attended. I stuffed them with crumbled blue cheese and hazelnuts and served them alongside cedar-planked salmon and roasted broccoli.
