THE preparation time for oven chips has been amended from 15-18 minutes to around eight weeks.
Following feedback from customers, all oven chips should be cooked at 200ºc for about two months before you plan to eat them.
An oven chip spokesman said: “If you want them to be crisp, yes. So plan ahead.
“Just leave them in there, turning them every seven or eight minutes, for 50-60 days until they’re golden brown and delicious.
Chip enthusiast Joseph Turner said: “I could just get a deep fat fryer, but then I’d be working class.”
