Steam both in a heavy saucepan with the olive oil until translucent. Add the dill tips and butter. As soon as the butter has melted add the rice. Put the stove on a low flame. Once the rice has absorbed the liquid, add a ladle of hot broth and mix thoroughly. Keep adding the stock until it is used up, approx. 30 min.
Tips: Once the rice is in the pot, stay on the stove. It can burn very quickly.
With a little parmesan the risotto becomes the main course.
