This is very informative. They key is that the goat meat is roasted only with salt via basting with salt water.
When you eat the roasted goat it is eaten with chili sauces and other condiments. Also sides like salads, chapatis and potatoes. This makes up for the goat meat being roasted only with salt, without herbs, BBQ sauces and other flavor enhancers.
