"My favorite drink is tomato juice!"
Translation:Mein Lieblingsgetränk ist Tomatensaft!
It's genuinely a thing in Canada as well, though I prefer the tomato-based V8 (eight vegetables, overwhelmingly tomatoes) when I'm looking for something savoury to accompany a meal or as an extra boost of veggies on its own. Certainly both tomato juice and V8 are used for cocktails, but have to admit I've never tried one. My parents used to use a third option when throwing parties in the eighties - Mott's Clamato (!) Juice, which was tomato juice with clam juice added. I'm pretty sure it's the basis for the Caesar cocktail, a version of the Bloody Mary, but again, not something I've ever tried...
No. It is a so called "Fugenlaut" (linking morpheme). That's a letter that gets introduced in between when you attach two words. In German it is usually an s or an n. It doesn't have any meaning of its own, it only makes pronunciation easier, because without it you would have two g's directly following each other.
