I am also making sweet potatoes and corn. Let me tell you that it was a BITCH to find sweet potatoes. Of course, today I also had the obstacle of no car because mine is at the dealer getting winter tires put on so I needed to go to about a million super markets by bus, which is fine, but then I needed to get everything home, which was decidedly more difficult. In the end I went to three different super markets and only Real had sweet potatoes and they are...different. They were marked "Israeli Sußkartoffeln" which translates to Israeli sweet potatoes so, yeah, fingers crossed they taste good. I was worried I wouldn't be able to find sweet potatoes at all because after I went through the potato section of Real I found nothing but they were actually in the imports section. They probably only had 10 potatoes total (but they were sizeable), I bought three and it cost FIVE euro. I think the potatoes cost more than the turkey.
Sigh, hopefully I will be updating later today to let everyone know how FANTASTICALLY it all went.
Wish me luck!
