I hate instant pot to, but actually its surprisingly good for thickening my chicken cacciatore, following the sw recipe they use to much liquid for my liking so have had to thicken it using this, gets a thumbs up from me for this.
I agree real mash is better. So is real mash with butter & cream, but, hey, where needs must! lol
I always have smash in the house. I too use it for thickening stews & slow cooker recipes (which always end up rather 'wet' with me). I make croquettes from it, use it in place of flour when coating things and make quicky cheese n potato pies with it. I use it one way or another a couple of times most weeks...I'm sure I do other things with it, but I just can't think! lol
