Herby hasselback potatoes

Method

1. Set one potato at a time in the bowl of a wooden spoon then, using a sharp knife, cut slices at 4mm intervals (the spoon will stop you cutting all the way down, keeping the potato in one piece).
2. Put the potatoes on a baking tray, then toss with olive oil, herbs, some salt and a grinding of pepper, making sure some of the herbs and oil get into the slits. Roast for 45-60 minutes until the potatoes are crisp and golden (see cook’s tip).
