Where’s the best place to store butter?
Keep butter in the coldest part of the fridge, preferably in its original packaging or an airtight container, at ≤ 40°F (4°C). Salted butter can be stored at room temperature in a covered dish for short periods, while unsalted butter should always be refrigerated. For long-term storage, freeze butter in an airtight container, leaving room for slight expansion.
How can you tell if butter has gone bad or expired?
You can tell butter has gone bad if it develops a sour or rancid smell, an off or bitter taste, or a slimy, moldy, or discolored appearance. Fresh butter should have a smooth, creamy texture and a mild, slightly sweet aroma. If it takes on a strong, unpleasant odor or tastes sour, it’s best to discard it.

What’s the best container for storing butter?
The original packaging is usually the best option for storing butter, as it helps protect against light and air exposure, preserving freshness.
