do you heat the tray up first in the oven before adding the chips, and add a good spray of frylight to the chips before putting them back in? I find that crisps them up nicely!x
I use red rooster or maris piper potatoes, part boil for 5 mins, drain,put back into saucepan & season with your favourite flavour, shake well, spray a shallow tray with frylight, place the chips in a single row on the tray, spray again then cook in a pre-heated oven at 180-200C cook for 10-15 mins remove, turn over then repeat, remove when browned.
Enjoy!
Have been making these chips for ages Don't bother with par boiling (but if in a rush do place in microwave !)
But the end results is SO dependent in the potato and this year has not produced good ones!
