Measure the whole grain rice and wash it in a sieve. Finely chop the onion and garlic cloves. Cut the chestnuts into larger pieces, roughly quarter them. Cut the parsley very finely.
Put all ingredients, including the spices, in a pressure cooker and stir. Set the pressure cooker to level II and cook for 20 minutes. Then place it on a cold stove and wait until the pressure cooker can be opened. Then open, stir, if necessary, season and season.
This amount is enough for 2 people if nothing is eaten with it. You can e.g., Serve with carrot vegetables or put a wreath of cooked carrots around the risotto. But this risotto also goes well with festive dishes, especially in the cold season.
