Heat the oven to 400 degrees farenheit / 200 degrees celsius
Trim and separate the 12 chicken wings and throw the tips. You will then have 24 pieces of chicken.
Put the wings in a large bowl and then add the salt, pepper, chili sauce and oil. Mix well
Take a plastic bag. Put the flour in the bag and then the chicken wings. Mix well to coat all the chicken wings with flour.
On a baking sheet, put some tin foil and lay the chicken wings in one layer.
Bake in the hot oven for 30 min. At this stage the chicken wings will look pretty ugly but don't worry...
Flip each wings so that the other side can bake. Put back in the oven for an additional 30 minutes.
