Wash and peel the potatoes. Slice thinly (about 2mm to 3mm) using a mandolin slicer.
Melt the butter, then add the rose harissa and salt.
Add the potatoes to the melted butter and mix well.
Pre-heat oven to 200ºC (fan assisted)
In an oven-proof dish of about 8 inches radius, arrange the potatoes upright, overlapping and at an even height. Starting with the white potato and then the red, alternate the colours as you move to the centre. The layers should not be tightly packed as we don't want to lose the crispiness.
Bake in the oven for 1 hour until the potatoes are golden and crispy on the top and cooked through inside.
