Cherry wood provides a sweet smoke flavour that still has enough robustness that it complements red meats such as beef and game well. Popular with small goods makers for mettwurst and other semi-dried sausages that are smoked.
Chunks are approximately fist-sized pieces of woods that provide a long-lasting smoke for your cook. They typically burn for much longer than chips; you can expect several hours of smoke in a traditional smoker and at least an hour in a grill or pit.
