Preheat oven to 220°C.
Cut the potatoes around half way through very finely across the whole potato. The finer you chop, the crispier they will be.
Place on a baking tray and spray liberally with low calorie cooking spray. Add Spicentice Chipotlec Rub to your potatoes and rub in, being careful not to break the potatoes.
Pop in the oven for around 30-40 minutes, making sure the potatoes are placed cut side up. Check occasionally to make sure they're not burning. Not that you need telling. Enjoy!
