This is maybe a bit of a mean thing to post and just to put in to context my mother in law is a good cook and pretty much everything she makes is delicious. However her mashed potato is always really gloopy. Maybe it's the potatoes she uses but she always adds a lot of milk and butter and then I think uses a stick blender which I feel is where the problem is. This time she put mozzarella in it. My wife and father in law are like mmm it's soo good and I know they are genuine and I'm thinking like really? Is it? I'll add a pic what do you think
