Wrap each potato in foil and put instantly on the brand new coals of a barbecue for 35-45 minutes, counting on the size of the potatoes. Insert a skewer into each one to look at that they’re cooked. (Alternatively, heat oven to 200C/180C fan/gasoline 6 and put the foil-wrapped potatoes on an enormous baking sheet. Bake inside the oven for 45 mins-1 hr or until the centre is mushy. As quickly as cooked, put beneath a scorching grill for 3 minutes until the pores and pores and skin is blackened and crispy.)
