If I make them, I parboil the potoates, drain them and make sure they are dry (otherwise you end up with soggy mess), spray a tray with frylight, put it in the oven for 5 mins, then put the potatoes on the tray, spray the pots with frylight and bake until they are done to your consistency (I like mine quite well done so do mine for a good 35 mins). The best frylight to use for chips in my opinion is the buttery one.
Mmm i love making my own chips! and i agree about the buttery frylight ... somthing else which is nice! is ... do the potatos .. slice up a pepper to to add to the bulk! .. then when almost cooked make a well and break an egg into it and put back in oven for a couple of minutes! ......... LOVELY
When i do this i have it with some WW spag and a couple rashers of bacon mmmmmm mmmmm
