I just had a Reuben sandwich made with good black Russian bread, cheap corned beef and Swiss cheese, sauerkraut that smelled like a fart when I cut open the bag, and Russian dressing. Reuben sandwiches are supposed to have Russian dressing on them but most restaurants use Thousand Island instead. The first one I had today was one of the best sandwiches I've had in a long time. Maybe it shouldn't amaze me how using the correct ingredients can make such a big difference. But it makes me wonder why more people don't do it.
According to Wikipedia, Russian dressing is a piquant American salad dressing consisting of mayonnaise, ketchup, complemented with such additional ingredients as horseradish, pimentos, chives, mustard, and spices. Thousand Island dressing is a creamy salad dressing and condiment made from a base of mayonnaise and usually ketchup or tomato purée and chopped pickles, and typically including a variety of other ingredients. In the United States, Russian dressing has largely been supplanted by Thousand Island dressing, which is sweeter and less spicy than Russian. When I used Thousand Island dressing on something not long ago, it was the first time I tasted it in several years, decades really. I used to like it on salads, but this time I found it to be too sweet and had an overpowering flavor. If you're trying to cover up the flavor of something like a Big Mac, I guess it works okay for that.
The Russian black bread I had was from Zehnder's of Frankemuth, like this loaf of theirs, except it was a sliced loaf. My friend's mom bought it and didn't like it, so she stuck it in her freezer. Before she came home from up north she asked me if I wanted it, and of course I said yes. It's liker pumpernickel + a little something extra. You can find several recipes online if you're interested in what the difference is. This loaf has vinegar and cocoa, in addition to things you'd expect, like molasses and caraway seeds. I found out there's such a thing as black cocoa. It's Dutch processed cocoa that's been processed more with alkali making it less acidic and much darker than regular cocoa. It's what makes Oreo cookies black instead of brown, and is good for making bread, brownies, cookies and cakes. Because Black Cakes Matter.
