Remove the skins from the peppers by putting them in a very hot oven
Steam the potatoes. On individual plates lay out the strips of pepper – this is a very decorative dish – and place on top a few strips of anchovy fillets. Pour a little of the anchovy oil over each plate.
Mix together the vinegar, oil and seasoning. As soon as the potatoes are cooked and can be handled, grate a ring of fluffy potato around the peppers on each plate. Spoon over the dressing and serve immediately.
