What is nordic krokan?

As an AI language model, I do not have any information about "nordic krokan". It is possible that you meant Nordic Krokant, which is a crunchy candy originating from Scandinavia. It is made by caramelizing sugar and mixing it with toasted almonds or hazelnuts to create a sweet brittle texture. Nordic Krokant can be used as a topping for ice cream or desserts, or it can also be eaten as a standalone snack. It is a popular candy in the Nordic region and is often associated with the holiday season.
