Choosing the Best Quality and Freshness

  • Look for potatoes with smooth, unspotted skins and no mold or other signs of decay.
  • Choose potatoes that are heavy for their size and feel hard.
  • For Japanese sweet potatoes, choose ones with smooth, bright-colored skins that don’t have any soft spots or wrinkles.
  • Sweet potatoes can have different-colored skins, but make sure the skin is whole and free of big cuts or bruises.
  • Choose medium-sized potatoes because they usually have a good mix of taste and texture.

Follow these rules for storing Japanese sweet potatoes as well as other sweet potato types to make them last longer and keep their quality:

  • For the best taste and texture, eat them within a week or two.
  • Cooked sweet potatoes can be kept in the fridge for up to 4-5 days in a jar with no holes.
