I have 1 leftover swede in my fridge, imported from Edinburgh by friends for neeps and haggis meal. It is a well-travelled swede, having made stopovers in London and Zermatt before landing in the veg cellar
Turnip is white on the inside, swede is yellowish. They taste different. They cook differently.
Turnip is in abundance here, but swede is hard to find and i love it too.
Migros may stock them, but very rarely. If they do, i buy a few, peel them, chop them, freeze them uncooked in batches - ready to be added to a soup.
So yes, my advice is to monitor local shops stocks, buy more than you need, freeze them. Or ask friends / family who plan to visit you from abroad to pack a couple of those. Our friends always bring a turnip and a bottle of fairy platinum for us - it's like an entry fee to switzerland...
Yes, , a dish detergent! It's seriously strong! It would be the end of the world for me if Fairy platinum stops to exist. There are two things i check at home like a junkie: swede stock in the freezer and fairy bottles in a whicker basket in the cleaning cupboard. Erm... And special treats supply for the neighbour's cat. I don't need much to feel high!....
And surely every one knows it was first found in Finland, rather than Sweden. Finland being at the time under rule of the Sweden might had influence on the name. Only edible food that can be made out of this hybrid of cabbage and turnip is traditional Finnish Rutabaga/Swedes cassarole...
