You can put it in the freezer (usually the temperature is 0-5 degrees) and eat it the next day. Waffles belong to the cake category. This freshly baked waffle usually has a shelf life of a few days. It is recommended to eat within 3 days. If it is a packaged waffle in a supermarket, it is not made now, but at room temperature. You don't need refrigeration in winter, but you can put it in the refrigerator in summer. The general warranty period is several months. As long as there is no cream on it (cream will melt and affect the taste), you can put it in the microwave to heat it up. Because it is cooked food, the heating time does not need to be long, and one piece is 20-30 seconds at most. Waffles at room temperature can be eaten directly without heating. Oh, you can eat it with or without heating.
