The general consensus is that salted butter can be safely kept at room temperature for up to two days, as the salt acts as a preservative. Unsalted butter, however, should ideally be refrigerated if not used within a day. Factors such as ambient temperature and humidity can also affect these timeframes, with cooler, drier conditions being more favorable for longer storage.
Signs That Butter Has Gone Bad
Spoiled butter may exhibit several signs, including a sour or off smell, a change in color (often becoming darker or developing spots), and a rancid or unpleasant taste. In some cases, visible mold may appear on the surface. If any of these signs are present, it is best to discard the butter to avoid potential health risks.
