Even if it's not a cliche that it was made while playing poker If you look at the ingredients that make up the Ruben sandwich, it's a really interesting dish Germany's Sour Crout, Switzerland's Emmental Cheese, Ireland's Cornbiff, and the United States' Russian Dressing gather to complete the Ruben sandwich It's an American recipe made up of immigrants from different countries I made sandwiches by collecting representative foods from each country, but it can't be bad, right? Each ingredient is delicious, but you can feel how much synergy it has when combined Corn beef has a soft yet strong scent of beef, and Emmental cheese has a strong flavor The two heavy ingredients are supported by sourcrout and Russian dressing, creating an amazing harmony It might be a bit of a hassle, but the key to this dish is preparing ingredients Rye bread, corn beef, sour cream, emmental cheese, Russian dressing It doesn't matter if you buy all the ingredients from the market and combine them, but it's a lot of fun for a cook to make them himself I'll post the recipe for Corn beef and Sour Crout of course This recipe contains Russian dressing
