2 egg whites, lightly beaten with a fork
4 tbsp sea salt
8 large baking potatoes, each pricked 2-3 times with a fork
Lactose free butter, to serve, if you like
Serves - 8
Heat oven to 160C/140C fan/gas 3. Put the egg whites and salt in 2 shallow bowls.
Dip each potato into the egg white to completely cover, then dab into the salt to cover in patches.
Carefully put the potatoes onto a baking sheet, pressing on any remaining salt, then bake for 1½ hrs.
Bake them for a further 1 hr at 200C/180C fan/ gas 6. Scrape off as little or as much of the salt as you like before eating.
