To moisten foods during cooking or grilling with fats or seasoned liquids to add flavour and prevent drying. In general, recipes in this cookbook do not call for basting meat and poultry with pan juices or drippings. That's because basting tools, such as brushes and bulb basters, could be sources of bacteria if contaminated when dipped into uncooked or undercooked meat and poultry juices, then allowed to sit at room temperature and used later for basting.
