Sometimes the skin of the boerewors (called the casing) bursts during the braai. More often than not it is the actual boerewors that is the culprit and not the casing. Too much fat in the wors can cause the casing to rapture – which is then not a bad thing! Bursting boerewors can also be your own fault. If your fire is too hot the casing will shrink faster than the meat…and the inevitable will happen.
