So Good Hammelsuppe (Mutton Soup)

A German Country Soup With Real Heritage

Hammelsuppe is the kind of soup grandmothers in southern Germany have been making for generations. Bite-size pieces of mutton simmer with celeriac root, leek, and carrots until tender, while cubed potatoes break down into the broth and thicken it from the inside out.

The finishing technique is what gives this soup its silken body. Fine farina sprinkled in during the last half hour adds a soft, almost porridge-like richness, and walnut-sized potato dumplings (kartoffelkloesse) drop in to bob in the bowl. The very last step, an egg yolk whisked into cream and stirred into the hot soup, turns it velvety without breaking.

Nutmeg and fresh parsley right at the end pull the whole thing together. The nutmeg is no afterthought, it’s the classic German pairing for celeriac and dairy that ties every flavor across the bowl.

Chef Tips

• Skim the foam off the surface during the first 20 minutes of simmering. That scum is what makes broths look cloudy.
• Temper the egg yolk before adding. Whisk a ladleful of hot broth into the yolk-cream mixture first, then stir back into the pot. Dumping cold egg into hot soup scrambles it.
• Cook the dumplings separately and add at the end. Boiling them directly in the soup turns the broth starchy and gluey.
• Use bone-in mutton if you can find it. Bones add deeper savor than boneless cuts.
• Salt at the end. Mutton releases salt naturally during a long simmer, and oversalting the cooking water turns the finished soup harsh.

Variations

• Substitute lamb shoulder for mutton if mutton is hard to source.
• Add a parsnip and a small turnip alongside the celeriac for a deeper root-vegetable bench.
• Stir in a splash of dry white wine before adding the egg-cream finish for an elegant twist.
