I am not sure if I am putting this in the right place..so please forgive me if I gooped up. My favorite recipe for mashed potatoes is using whipping cream instead of milk. It is located by the milk at the grocery store. I just thought I would recommend it since holidays are coming up. Using half and half, makes the mashed potatoes so much better. I use butter and salt and pepper with it of course too. I highly recommend it:)
I make my mashed potatoes with sour cream and cream cheese. Very rich, of course, but delicious. Also, it can be prepared ahead and frozen, then pop in the oven for 1/2 hr. before serving. Always a big hit!
