PASTE: Without shaking the can, skim off two tablespoons of the coconut cream and add it to a sauté pan set over medium-high heat. Add the Panang curry paste along with the peanut butter and cook for 1 minute. Add the chicken and stir to coat, cook for 1-2 minutes. If at any point the sauce begins to stick to the pan, add a couple tablespoons of water to deglaze. Stir in the remaining coconut milk, starting with 1 1/2 cans (adjust with more later if desired.) Add the kefir lime leaves, fish sauce, brown sugar, sliced onion, and red bell pepper. 

SIMMER: Allow the curry to come to a simmer, lower the heat and let simmer for 2-3 minutes or until the chicken cooks through. Taste and adjust with additional coconut milk, sugar, tamarind, or fish sauce as desired. Turn off the heat and stir in the basil. Serve warm with rice or cooked rice noodles.
