Swedish dinner

We were hanging out in a pub in Waterloo, after having paid a visit to the hospital again. Tim asked about the dinner. A Swedish one, tonight, as we had bought loads of meatballs. I was making an attempt to have Tim speak Swedish:

I: So, what are we having for dinner?

T: Köttbullar [meatballs].

I: And?
T: Potatis [potatoes].

I: And?

T: Gräddsås [creamy sauce].

I: And?

T: Eeeeh, wine?

I: No, I was thinking of a bärprodukt [berry product].

T: Eeeeh, stones?

Ha ha ha! I just had to laugh out load. Where did that come from? But I soon got my explaination, when I worked out that Tim thought I said bergprodukt [mountain product]. It was lingonberry jam I had in mind, but stones were definitely more innovative!
