In a bowl, put all the spices [cayenne,paprika,mustard,garlic,black pepper,onion,salt] and make a mixture.

To the mixture add the chicken and mix it properly(make sure that spice mixture is applied well for good taste) and marinate it for 30 mins in refrigerator.

To another bowl put buttermilk and some hot sauce (and mix it well to get a mixture) and to a plate put some flour for coating.

Remove the chicken from marination, then preheat the oil to deep fry it.

Dip the chicken into the buttermilk-hot sauce mixture and then coat it with flour and then deep fry the chicken till it's golden brown.

And now your chicken is all ready. Serve it with hot sauce for more good flavour and enjoy your meal.
