Many folks use aluminium foil during grilling since it accelerates the cooking process. This kind of BBQ wrapper also keeps the meat warm. However, if you’re after bark, this item won’t work. Wrapping meat in aluminium foil while grilling is not recommended since it makes the crust soggy. Heat can produce steam during the cooking process and eventually soften bark. If you do want to wrap the meat, do so once the bark is obvious and make use of butcher paper.
