| Thawing and Grilling Method | The instructions are to move it from the freezer to the refrigerator and half-thaw it for about 5–6 hours, then, in a well-heated frying pan without oil (or with a little oil if it tends to stick), brown one side over high heat, flip it, cover, and steam-grill over low heat for about 10 minutes. Clear juices coming out when pierced with a bamboo skewer or similar are given as the sign that it is done. If grilling from frozen, the instructions say to brown it well and allow a longer steam-grilling time of about 12–15 minutes.

Suitable as a Gift?
The product description advises that if you’d like noshi or a message card, let the shop know in the order notes or similar when orderingSource: product description. The type of noshi inscription and whether a gift box or gift wrapping is available are not confirmed.
The seller’s guide image says this product is delivered in simple packaging with 6 per pack, and that for those concerned about discoloration, or for gifts, the shop also sells a vacuum-packed versionSource: image within the product page (guidance on packaging). If appearance matters for your gift, it’s worth checking whether this or the vacuum-packed product suits you better. If you’re considering this as a gift, checking the following can also help avoid any mix-up:
- Please ask about the type of noshi inscription and the form of wrapping individually in the order notes
- Whether it can be delivered at a date/time the recipient can receive it, since it is a product kept frozen
- Whether the recipient has room in their freezer for 150g × 12 (1.8kg)
Some reviews mention using it as a birthday present or as a gift to relatives (Source: Rakuten customer reviews, viewed September 26, 2026).
