METHOD
Step 1
Bring a large pan of salted water to the boil. Add the potatoes and cook until just tender, 12–15 minutes, depending on size.
Step 2
Meanwhile, add the cumin, coriander and fennel seeds to a hot dry frying pan and toast for 2 minutes until fragrant. Crush the toasted seeds, using a pestle and mortar; set aside.
Step 3
Heat the grill to high.
Step 4
Drain the potatoes and allow them to steam-dry in the colander for a minute.
Step 5
Place the potatoes on a sturdy baking tray. Brush or sprinkle them with some oil and grill until the upper side is crispy and evenly browned, about 5–7 minutes. Turn the potatoes over and repeat to crisp and colour the other side.
