Brown chips and supermarket potatoes

[George the Pigman]

Santa brought me a fancy deep fat fryer for Xmas and I used it to make chips from my stored allotment potatoes. Various potatoes in various states of squidgyness gave excellent crisp light coloured chips.
When the allotment spuds ran out I bought supermarket ones.
All the ones I bought now give brown sweet soggy chips. Anyone any ideas what is happening? I've tried changing the oil and it makes no difference.

I'd guess too high a water content in the supermarket ones.

Just not a chipper spud..

My mum always said...best mash, chips and potato soup is made from 'old' potatoes...and we never had any of these foods from fresh stock until they were stored some time in cellar.

Like already said...it probably is to do with water content...and added to that, stored/older potatoes have had their sugars turned into starch..all those sugars make new spuds taste lovely and sweet.

What variety was it, it normally says on the packet.  Suggest you try a different type and avoid that one next time.

floury spuds are better for chips you may be using a waxy type.

Most of the local chippies fry Maris Piper or Maris Bard. Can you use beef dripping in the frier? Thats a very special flavour!

[George the Pigman]

I've used various supermarket ones but the last lot I used was Maris Piper which was claimed to be an "all rounder"

ALWAYS get this with supermarked spuds

Yeah, most of the ones from the supermarket fry about as well as a Rocket that's been left a bit too long.... Kestrel makes nice chips in my experience (on my rather alkaline soil) as does Arran Victory, and if I seriously didn't trust its fragility the Yetholm Gypsy is simply fabulous fried or roasted..... If you can ever find Lumper (and get the blasted thing to grow without getting blight) then it's well worth trying it fried.... you get this almost carmelised glazed finish on it that is unlike aything else I've ever had....also Pink Fir Apples, once they've softened slightly .... gorgeous...
