Preheat your oven to 200C. Hasselback your new potatoes and artichokes by slicing carefully down with at least a dozen cuts that run parallel almost entirely down through the potato but keeping it intact.
Place onto a roasting tin and drizzle with oil and sea salt. Roast for 25-30 minutes, or until golden brown and crispy.
Top with freshly chopped chives, anchovies and baby watercress and serve warm.
