Yes, cold temperatures can help keep butter from spoiling quickly, even if it's not stored in the refrigerator. Butter is sensitive to heat and light, and higher temperatures can lead to the growth of bacteria and spoilage. If you can't or prefer not to store butter in the refrigerator, keeping it in a cool place can slow down the spoiling process.
Ideally, butter should be stored below room temperature (typically below 70°F or 21°C) and away from direct sunlight. A cool pantry or cupboard can be suitable for short-term storage. If the ambient temperature is relatively low, especially during colder seasons, you can store butter on the kitchen counter without it turning rancid too quickly.
However, it's important to note that butter left at room temperature will still have a shorter shelf life compared to refrigerated butter. The colder temperatures in the refrigerator significantly slow down the growth of microorganisms and the oxidation of the butterfat, extending its freshness.
If you plan to keep butter at room temperature for an extended period, consider using a butter keeper or butter dish specifically designed to maintain a cooler environment around the butter. Some of these dishes have a water-filled base that creates a seal to keep the butter fresh.
To summarize, while cold temperatures can help prolong the freshness of butter when not stored in the refrigerator, it's still essential to use it within a reasonable time frame to ensure it remains safe for consumption.
