General Guidelines for Leaving Butter on the Counter
Butter can typically be left on the kitchen counter for a few days without posing a significant health risk, provided that it’s stored correctly. The key is to use a butter dish with a cover, or a butter bell or crock, which can help keep out contaminants and maintain its freshness. Here are some rules of thumb to follow:
1. Keep the butter covered to protect it from contaminants and odors.
2. Place butter away from direct sunlight or heat sources.
3. Regularly check the butter for signs of spoilage, such as an off smell, mold, or discoloration.
