Tapa is dried or cured beef, mutton, venison or horse meat, although other meat or even fish may be used. Filipinos prepare tapa by using thin slices of meat and curing these with salt and spices as a preservation method. Tapa is often cooked fried or grilled. When served with fried rice and fried egg, it is known as tapsilog (a portmanteau of the Filipino words tapa, sinangag and itlog [egg]). It sometimes comes with atchara (pickled papaya strips) or sliced tomatoes as side dish. Vinegar or ketchup is usually used as a condiment.
