Bananas-Bananas and the fridge are a no-no. Bananas, like many other fruits, ripen at room-temperature. The moisture and cold air in the refrigerator will cause the bananas to go rotten.
Berries-Berries do well at room temperature as well. The moisture from the refrigerator can lead to soft, mushy berries…especially raspberries.
Tomatoes-Tomatoes placed in a cold refrigerator develop a mealy texture that occurs from the cold air and moisture. To get the best flavor from tomatoes, allow them to sit on the counter at room temperature.
