How to Store Hoshiimo
Hoshiimo isn't as delicate as fresh confectionery, but it does hold moisture, so storage deserves a little care. The basics: unopened, follow the package; after opening, seal and refrigerate; for the long term, freeze.
Unopened
Keep it away from direct sunlight, heat, and humidity, and follow the storage instructions and date printed on the package. In cold winter months a cool, dark place is often suggested, while from spring into summer refrigeration is usually recommended even before opening.
After opening
Once opened, hoshiimo is exposed to air, which invites drying and mold. Close the bag tightly or move it to an airtight container or storage bag, keep it in the refrigerator, and finish it early regardless of the printed date.
Freeze for the long term
If you can't finish it soon, the commonly suggested method is to wrap each piece in plastic wrap, place them in a freezer bag, and freeze. To eat, thaw naturally in the fridge or at room temperature. A light toasting after thawing adds fragrance and a pleasant change of texture.
When not to eat it
If anything seems unusual — green, blue, or black spots, fuzzy growth, a sour smell, sliminess — don't eat it. For telling mold from the white powder, see the 'About the White Powder' page. When in doubt, check with the seller you bought it from.
