I cooked squash on parchment on a dairy tray that hadn’t been used in a few weeks.
I want to use the squash in a soup and cook it in my pareve pressure cooker but I don’t want to make the pressure cooker stop being pareve.
Will the squash make the pressure cooker dairy?
It may be cooked in your pressure cooker, and it will not make it cooker dairy. He reason is that although the Rema is stringent not to cook food from a milky pot in other pots, that is only if the pot was used within the last 24 hours. In your case it wasn’t, therefore it is permitted.
