Lemon Tuna Risotto

I love risotto! So many variations, so easy to make, and always
delicious.

This one is with carnaroli (my fav risotto rice) with sauteed onion,
garlic, very finely diced celery and a good pinch of salt.

Continously stirred with one ladle at a time of 70/30 hot stock and
white wine for about 25mins.

Finished by stirring through lemon zest, chunks of tuna, and lots of
freshly grated parmesan.
