1. Grill / Roast : need short period of time of cooking, less spices, retain the quality of the meat.
2. Braise / Stew : need long period of time of cooking, more spices, enhance the quality of the meat.
Well, both of them have different art of cooking.
In my opinion whatever the cooking method that we use to our meat as long as we can get good quality and good taste as we desire that will be very okay. The matters are how we choose the quality of the meat (means the part and the freshness) and the cooking method that we want to apply to our meat.
knowing the character of our meat is also important. For example we can not use tenderloin to make rendang which need to braise and get the chewy texture of the meat, because tenderloin has soft texture, if we braise it, it will be floss. and for economic reason use tenderloin for rendang will cause high cost.
not all of the expensive goods has a good quality, and not all of the cheap goods can not be good.
