Siba’s tip…

Instead of roasting the potatoes after boiling, you can shallow fry them in duck fat until they are crispy. When I am pressed for time, this is the cooking method I use.

You can also substitute the duck fat with canola oil and 2 spoonfuls of ghee. Ghee is clarified butter, which is butter that has been melted and then all the floating solids removed by skimming them off with a spoon. It’s these solids that often make the butter brown or ‘burn’ quickly.
