Thai Red Curry Chicken with Basil

i've been thinking about making this for a while. this dish would have been not spicy enough so i added in chili oil even with the serrano pepper.  future recipes i will add 2 serrano peppers.

• 13 ¹⁄₂ ounces coconut milk, shaken well
• 1 ¹⁄₂ lbs chicken breasts, raw, sliced into bite size pieces

• 2 tsp. sugar
• 2 tsp. fish sauce
• 2 red bell pepper, sliced thin
• 10 - 15 large basil leaves
• salt and pepper
• 1 tsp red chili oil 
• basil for garish

Directions:

1.    Heat the oil in the frying pan over medium heat. saute onions, serrano pepper, and garlic.  5 min.

2.    Add the curry paste and simmer for 2 minutes, so that it is dissolved, fragrant and foaming.

3.    Stir in the can of the coconut milk. Cook over medium heat for 5 - 8 minutes, stirring occasionally.

4.    Add the sliced chicken. Simmer for 4 minutes.

5.    Stir in the sugar, fish sauce, basil, and bell pepper. Simmer until the chicken is cooked, about 10 minutes
