Not Too Long. Butter should be taken out of the refrigerator 10 to 15 minutes before using, advises the U.S. Department of Agriculture. But it takes longer than 15 minutes to bring butter to room temperature, which many recipes call for. Many professional bakers bring butter to room temperature overnight.
Timing Is Everything. Indoors, you can safely leave a sandwich out for up to two hours after making it, according to the USDA. After that, bacteria starts to multiply rapidly. In hot weather the margin of safety is cut to one hour. Don't take chances. Refrigerate sandwiches or pack your lunch box with an ice pack.
