I will enjoy a second half of a bowl when it happens. I do not do this consistently…… much of the time I complete a bowl when I start. But if I do not, and it rests for a while…. I tend to enjoy the second 1/2 because to me it has its own different, nuanced flavors that are usually enjoyable and interesting. So, for me it is not something I purposefully seek to do, but it does occur and is enjoyable to me.
However, if for some reason, YOU do not like it, there is no harm or foul in knocking out the half spent bowlful and reloading with fresh…. if that is your preference.
