U' Cardone

U' cardone is the great festive primo of Molise, set down in a nineteenth-century manuscript but older than that, and shared with the neighbouring Sannio and Abruzzo, where a cardoon soup opens Christmas lunch in much the same way. Cardoons were a winter field vegetable of the poor, their bitter leaf-ribs made good with slow trimming and long soaking; the capon broth and the little meatballs raised the dish to the year's most important meal. It is patient, labour-intensive cooking, begun the day before, that gathered the pastoral-contadino household around a single warming bowl. The egg beaten into the broth, and the raw egg cracked into the bowl, are the country cook's way of enriching a soup without meat to spare.

The cardoon keeps a faint, clean bitterness and a tender, celery-like bite under the golden broth, which is deep and savoury with capon. The little meatballs are soft and well-seasoned, the egg hangs in silken threads, and the whole bowl is warming and homely, a slow, comforting soup for a cold feast day.

Soaking the cut cardoons in lemon water does double duty: the acid slows the enzymes that would brown the exposed flesh, and the long steep leaches out the water-soluble bitter compounds of the thistle, which boiling then reduces further. In the finishing pan the capon broth carries dissolved gelatin from the bird's bones and connective tissue, which gives the soup its rounded body and mouth-feel. When the beaten egg is stirred into broth held just below the boil, its proteins coagulate on contact at around seventy degrees and set into the fine stracciatella threads; the same coagulation gently cooks the whole raw egg when the near-boiling soup is poured over it in the bowl.
