Can you mix pretzels butter and sugar then bake them leave out of refrigerator all night to make pretzel salad the next day or should it be refrigerated?

It is recommended that pretzel salad be refrigerated if not consumed immediately to maintain its quality and safety. Leaving the mixture of pretzels, butter, and sugar out at room temperature overnight may increase the risk of bacterial growth and potential food safety issues. Refrigeration helps slow down the growth of bacteria and keeps the salad fresher for a longer duration. Therefore, it's best to refrigerate the pretzel salad after baking and let it chill overnight to ensure optimal taste and safety.
