The real key to a great-tasting roast (even an everyday wallet-friendly rump roast, the kind I grew up on) is to season it ahead of time. Whether you call it a rub, a dry brine or a dry marinade, make sure to do it at least an hour in advance. In truth, a night in the fridge is really the ideal way for the meat to absorb the seasoning’s flavors. It actually makes things easier for the cook, too. All you have to do is pull it out and let it to come to room temperature, and it’s ready to go.
