No chicken involved. Cologne specialty. - Author: Andrew Lekashman - Tags: Germany, Submarine Sandwiches, Käse & das vegetarische Brötchen, #auto-imported **🇩🇪 Germany** · Family: [Käse & das vegetarische Brötchen](https://onesandwich.com/tag/das-kaesebroetchen/) · Region: Cologne · Bread: roggenbrotchen --- Ingredients roggenbrötchen · gouda · mustard · butter · onion The first thing to know about the *Halver Hahn* is that there is no chicken in it. The name is Kölsch dialect for "half rooster," and ordering one in a Cologne *Brauhaus* expecting poultry is the joke working exactly as intended. What arrives is a *Roggenbrötchen*, a rye roll, split and buttered, with a thick slice of mature Gouda and a generous dab of mustard. The whole appeal rests on that one decisive topping: a serious wedge of aged cheese on dark bread, nothing more. The craft is in the rye and the age of the cheese, because with so few parts each one has to be right. The roll is a dense *Roggenbrötchen* with a tight, slightly sour crumb and a chewy crust, the kind of bread built to stand up to fat and not go limp. The Gouda is the argument and it should be properly matured, firm and a little crystalline, sharp rather than the soft mild block, cut thick enough to be the substance of the thing rather than a garnish. Butter goes on the cut faces, the cheese sits on top, and the mustard, the medium-hot Rhineland sort, is daubed beside it or directly on the slice. The bind is the butter against the rye and the mustard cutting the fat of the cheese. Onion rings and a *Gewürzgurke* are the usual companions on the plate, sharpening each bite. A good one is balanced and bracing: dense bread, assertive aged Gouda, the mustard hot enough to register, eaten with a knife and fork alongside a *Kölsch*. A sloppy one is a young rubbery cheese on a soft white roll instead of rye, no real mustard, the whole point of the contrast lost. The variations are restrained, as a dish this spare tends to be. The cheese can run from a medium Gouda to a sharply matured one, the *mittelalter* against the *alt*; some houses scatter raw onion over the slice, others serve it strictly on the side; a few crack pepper across the top. The closely related plain *Käsebrötchen* family across the rest of Germany sits at the soft and mild end of the same idea, and the *Strammer Max* and its cousins crowd egg and ham onto bread in a different register entirely. That whole open-faced cured-and-fried tradition runs along its own line and deserves its own article rather than being crowded in here. --- ## More from this family Other [Käse & das vegetarische Brötchen](https://onesandwich.com/tag/das-kaesebroetchen/) sandwiches in Germany: - [Avocado Brötchen](https://onesandwich.com/avocado-brotchen/) - [Brezel mit Butter und Schnittlauch](https://onesandwich.com/brezel-mit-butter-und-schnittlauch/) - [Frischkäse Brötchen](https://onesandwich.com/frischkase-brotchen/) - [Gurkensalat Brötchen](https://onesandwich.com/gurkensalat-brotchen/) - [Handkäs mit Musik Brötchen](https://onesandwich.com/handkas-mit-musik-brotchen/) - [Hummus Brötchen](https://onesandwich.com/hummus-brotchen/) - [Käse-Marmelade Brötchen](https://onesandwich.com/kase-marmelade-brotchen/) - [Käse-Tomaten Brötchen](https://onesandwich.com/kase-tomaten-brotchen/) [See all Käse & das vegetarische Brötchen sandwiches →](https://onesandwich.com/tag/das-kaesebroetchen/)
