You do realise, I hope, that a remark like that is the equivalent of going into an Apple forum and saying "iPhones suck", or perhaps into the Celtic ground on match day wearing a Rangers scarf? i.e. something between a good way to start a fight and an inventive form of suicide.
Mashed potatoes? With a
blender?
Okay, I'll preface my remarks by saying, quite categorically, it's personal taste. If that's genuinely how you like your mash, then it's how you like you mash. And so be it.
But, and I suspect the cheffy types around here will agree (and will be interested to see what they say), it's FAR from the recommended method.
The logic is that potatoes are basic just a bag containing starch, some sugars, water and a few nutrients (the latter mainly in the skin). And if you want light, airy mashed, you need to be quite careful in how you do, and don't, prepare them. But most people will tell you that the art is in not destroying the starch molecules, but in keeping them together, whilst getting some butter/milk/cream/cheese/other flavourings (delete to taste) to coat the potato evenly, and while getting air in to keep them light.
Lots of people will tell you the best method is a firm,
wire masher. Others swear by ricers. Others like a slow hand-mixer, but most will tell you that a blender is FAR too aggressive for a "proper", smooth but light mash, because the high-speed blades destroy those starch molecules and you can be left with a gloppy mess. How gloppy depends, in part at least, on how you cooked the potatoes and probably even more, on what potatoes you used to start.
So, once again, I'll stress .... if
you like the mash you get as a result, then you do. Period. Just as long as you've tried it the "proper" way, and prefer the effect of the blender. I've tried it, and don't.
And to be clear, blenders are phenomenally useful little devices, and that Kenwood is probably as good as most and better than many. I find a little more effort (and the blender method is certainly easy) pays off in the result.
Nonetheless ..... blender .... mash? MASH! Sacrilege.
