A common kitchen question throughout the ages seems to be whether or not to refrigerate butter or leave it out on the counter. A recent Twitter poll showed that over 75% of people leave it out on the counter. According to food safety experts, that is perfectly fine. They do suggest following a few simple rules: use pasteurized butter, salted is best because the salt helps keep the bacteria away, store it in an air-tight container and if you do leave it out toss it after 2 weeks max.
