Rinse and wash the potatoes very well and then slice to make wedges (no need to peel the potato skin).
Take a big mixing bowl and add cornflour and all the spices and mix well.
Heat enough water in a big pan and add 1 tsp salt.
When water starts boiling add the potato wedges and boil for 5 minutes.
Drain and pour some tap water on the wedges to stop cooking further.
Add the drained potato wedges in the dry cornflour and spice mix and mix properly so all sides will coat with the mix.
Heat enough oil in a wide deep pan and heat on medium high.
Now gently add some fries in the hot oil, don't add too much in a batch.
Fry on medium to medium high flame so they will cook from the inside too.
When the wedges turn golden from one side then turn the side and cook from other side.
When they turn golden and crisp from both the sides then remove from the pan on a paper towel to remove the extra oil.
Serve the hot crisp wedges with a sauce or dip of your choice.
