In general, English muffins do not need to be refrigerated and can be stored at room temperature for up to a week, depending on the brand and recipe. Storing English muffins in the refrigerator is not necessary and may result in them becoming stale faster or absorbing unwanted odors from other foods in the refrigerator.   To keep English muffins fresh, it's best to store them in an airtight container or resealable plastic bag at room temperature in a cool, dry place, such as a pantry or a bread box.   If you live in a hot and humid climate or if your kitchen tends to be warm, you may want to store English muffins in the refrigerator or freezer to extend their shelf life. However, it's important to note that refrigeration can potentially make English muffins lose their texture and become more moist or doughy.
