Liver Roasted in the Oven

Ideally, liver should not be roasted in the oven, but rather on a grill in an open area. Even in a grill that can be closed, it is forbidden to close it while roasting liver, because when the oven is closed, the steam rises and fills the roasting space, and this is considered cooking. If it was roasted in a closed oven, the oven must be purged. Regarding the liver, according to the Shulchan Aruch, it is permitted, similar to liver that was cooked: the liver is permitted, but the utensil is forbidden. According to the Rema, the liver is forbidden. However, there are those who are lenient to roast in the oven, and this leniency is only valid if the oven is open, or if it has a chimney like in an industrial oven, or even in a home oven provided the door is open. But according to the law, those who are meticulous do not permit this leniency.
