1. Salted vs. Unsalted Butter
Salted Butter : Salt acts as a natural preservative, making salted butter more resistant to spoilage. It can safely stay on the counter for up to a week if stored properly.
Unsalted Butter : Without the preservative effects of salt, unsalted butter is more perishable and should ideally be refrigerated or frozen for long-term storage.
2. Temperature Matters
Butter is safe to leave out if your kitchen stays below 70°F (21°C) . In warmer environments, butter can soften too much or even melt, creating conditions where bacteria may grow.
3. Air Exposure
Butter left uncovered is more susceptible to picking up odors from the environment or going rancid due to oxidation. Always use a covered butter dish to protect it from air and light.
