Well, the classic stuff is probably soft drinks and sweets

If you get the chance you should absolutely try the following drinks:

Pommac - An old classic soft drink thay is matured in oak barrels, it is often drunk on NYE by children who want to toast in the new year, and by adults (like me) who has to drive later… https://en.wikipedia.org/wiki/Pommac

I had a guy from the UK try Pommac once and his comment was “weird!”

Then we have a very similar soft drink called Champis, it is less fancy than Pommac, but is great: https://en.wikipedia.org/wiki/Champis

Finally we have a more modern version called Trocadero, this is a drink from the 50s that taste sort of like apple and orange, it contains caffine and goes fantastic with pizza! https://en.wikipedia.org/wiki/Trocadero_(drink)

Sweets, Sweden and Fennoscandia are well known for our salmiak, I am not a fan…

Hallonbåtar however are fantastic, they are jelly candies made from raspberry jelly and shaped into boats.

Center and Plopp are choccolate with a soft toffee filling, they are fantastic.

If you need a camping stove, the Triangia stove is a classic, it uses a silent spirit burner and is rugged and dependable.

That is probably what you can easily get that I can remember off of the top of my head
