Toss the chicken with a cup of creamy coconut milk and as much piri piri as you can stand. Let marinade all morning, or preferably overnight. Turn the chicken once or twice to ensure it gets all over the chicken. TIP: If you score the meat, the marinade penetrates the chicken more thoroughly.
The next day, start cooking. Grill the chicken over medium heat (about 350F), until cooked through and the juiced run clear, about 40 minutes. Preferably, keep the chicken just off the direct heat.
Turn once and baste a couple of times with more marinade.
Serve with french fries or coconut rice and extra piri piri.
