Heat oven to 220C/200C fan/gas 7.
Rub a little oil over each potato and
put on the top shelf of the oven. Bake
for 20 mins, then turn down the oven
to 190C/170C fan/gas 5 and bake for
45 mins-1 hr until the skin is crisp
and the flesh soft.
Cut a cross on top of the potato,
squeeze the sides, add a dollop of
soured cream and your favourite topping. (Please note: the nutritional information below is for one jacket potato with soured cream and cheese topping.)
