I roasted potatoes, turnip, cabbage and onions. The cabbage and turnips are well roasted, kind of charred but I don't mind the taste. I tried to turn all of this into a soup and of course, I ended up with gluey potatoes. I barely blended them using a stick blender. I used gold potatoes. I was thinking of turning into a pot pie type of pie because it is so thick. Any suggestions?
