Preheat the oven 180C/356F/Gas mark 5.
Line and grease a baking tray with parchment paper and set aside.
Place the paprika, onion granules, garlic granules, parsley thyme, black pepper and pink salt in a spice grinder.
Mill into a fine consistency and set aside.
Cut the sweet potato in half lengthways (you may need to cut the potato the other too if you want short fries).
Cut the sweet potato halves into fries (the same size if you can) just less than ½ inch in thickness.
Bring ¾ filled saucepan of water along with the apple cider vinegar and pink salt to the boil.
Once boiled, carefully place the fries in the saucepan and parboil for approximately 8 minutes.
The fries should be slightly soft and the colour should be transculent. Test the readiness by using a fork.
Carefully drain off the fries in a colander.
Use kitchen towel to thoroughly blot the fries dry.
Place the fries in a zip lock or a tie handle bag.
Drizzle the oil of your choice into the bag.
Secure the bag by zipping or tying the handles of the bag.
Shake the bag to ensure each of the fries are completely coated with oil.
Open the bag and then pour in the seasoning, seal the bag and shake the bag again.
Arrange the fries onto the baking tray, spread them out to ensure they don't overcrowd.
Bake in the oven for 30-40 minutes, carefully turning them over halfway until they are golden brown (keep a watchful eye on them incase some brown quicker than others).
Once done remove from the oven and serve accordingly.
