Sweet Potato Selection
Select tubers with tight, unwrinkled skins with no blemishes or bruises. Prime season is from October to January but they are available sporadically throughout the year. They're great for Fall recipes.
Sweet potatoes generally do not store well, except under ideal conditions, and bruised ones rapidly deteriorate. Unfortunately, when sweet potatoes begin to go bad, you cannot just cut away the bad part, since the damage will be reflected in the flavor of the entire potato.
For the most part, sweet potatoes can be used in any white potato recipe, particularly the pale variety.
Sweet Potato Storage
Stored in a dry, dark, cool (55 degrees F.) place, sweet potatoes can last up to three to four weeks. Otherwise, plan on using them within one week of purchase and do not refrigerate raw tubers.
Canned sweet potatoes are readily available year-round, and are often confusingly labeled as yams.
Cooked sweet potatoes may be stored in the refrigerator in a covered container for 4 to 5 days.
To freeze, pack cooked sweet potatoes in an airtight container, leaving 1/2-inch headroom and freeze for 10 to 12 months at 0 degrees F.
