Fortunately like most things that start with the word ‘boer’ this wors is not fickle. You can microwave it, leave it in the sun or even braai it frozen.
The best way to defrost boerewors is the same as the best way to defrost all meat, and that is to take your boerewors out the freezer well in advance and place it in the refrigerator to defrost very slowly. This will prevent the boerewors from losing moisture. Defrosting it at room temperature will go a little faster and is absolutely fine, but just not “perfect”. If you’re in a hurry and want to defrost it in tepid water, please note two things; that the water is not too hot, as too hot water will start cooking the meat; secondly, make sure the wrapping is waterproof.
