Sweet potatoes will often turn hard and bitter when kept in the fridge
If you’re just as obsessed with sweet potatoes as others, your natural instinct might be to keep them in the refrigerator. Want our advice? Don’t do that. The cold temperature and the moist environment of a fridge will actually cause damage to the cell membranes of a sweet potato, and this can leave it feeling hard and bitter.
As if that wasn’t bad enough, the hard potatoes will then be difficult to cut and take even longer to soften when you boil or cook them. To maintain the soft and sweet texture and taste of sweet potatoes, keep them in a cool and dry cupboard in something that allows for a lot of airflow.
