Heat the oil in a saucepan, fry the leek rings and diced ham in it for a short time. Add the rice and stir well. Pour in the broth and cook for 15 minutes.
Add the cream (if the rice is still very soupy, raise the temperature a little and let the rice boil down while stirring before adding the cream) and cook for another 5 minutes. Season to taste with the processed cheese, salt and pepper.
Tip: The recipe can be modified by frying a small amount of beef tartare instead of ham. Both are popular with children. For smaller children of around 1 year old, one portion can be mixed with a little extra liquid and pureed.
