Hvidkaalssuppe med Flaesk

By January in Denmark the root cellars are doing the work the gardens cannot. The light is thin, the wind off the Kattegat has teeth, and the vegetables that made it into storage in October are what sits on the kitchen counter now. White cabbage, onions, carrots, a knob of celeriac. This is the month hvidkaalssuppe belongs to, and it has belonged to it for longer than most Danish dishes can claim.

The shape of the soup is older than the recipe. A pork shank simmered slowly in water until the meat surrenders, the broth strained clean, the cabbage cooked in the broth at the end so it keeps its body. The meat comes to the table on its own plate, sliced thick, with rugbrod and a pot of sharp mustard beside it. You build your bowl as you go. A spoon of soup, a bite of pork with mustard on dark rye, back to the spoon. This is faellesspisning, the shared meal, in one of its oldest Danish forms.

What I want you to pay attention to is the clarity of the broth. Hvidkaalssuppe is not a thick soup. It is not a stew. The beauty of it lives in the clean, honest broth that tastes of pork and cabbage and almost nothing else, and that clarity comes from two things: starting the pork in cold water, and skimming the foam patiently before anything else goes into the pot. Do those two things with care and the rest of the soup will reward you. You'll know when it's right because the broth will look like pale amber in the bowl, and the cabbage will float in it like ribbons in a window.
