To keep your Un Kurabiyesi fresh and preserve their delightful texture, it is crucial to store them correctly. Once completely cooled, transfer the cookies to an airtight container to prevent moisture from softening them. Ideally, they should be stored at room temperature, where they can last for about a week. For longer-term storage, you can freeze the cookies, but it’s recommended to layer them with parchment paper to avoid sticking. When you want to enjoy a cookie from the freezer, simply allow them to thaw at room temperature. Avoid refrigerating them, as this can cause them to become too soft and lose their signature crumbly texture. With proper storage, you can relish the buttery goodness of Un Kurabiyesi for days, making them a perfect treat to enjoy anytime!
