Mainland Greek Kreatosoupa Avgolemono (Κρεατόσουπα Αυγολέμονο)

Mainland Kreatosoupa Avgolemono is Sunday's beef soup: shin or shank boiled patiently with onion and celery, the broth deepened with carrots, potatoes, and rice, then finished with egg and lemon. In Macedonia, Thessaly, and the villages of Epirus, this is the kind of pot that goes on before the day takes hold. The meat must be collagen-rich, not neat lean cubes. That is what gives the soup body before the eggs ever arrive.

The one method that decides it is the avgolemono. You whisk eggs with lemon, then warm them with hot broth a ladle at a time before they meet the pot. Egg sets around 65C, so rushing gives you white threads and sour scrambled bits; patience gives you a pale, silky soup that tastes of beef, lemon, and winter.

I keep the vegetables plain because this soup was never trying to be clever: carrot, potato, celery root if you have it, rice enough to thicken but not turn the pot into porridge. My grandmother Despina would have set the boiled meat in the bowl in generous pieces and passed extra lemon at the table. A recipe written down is a recipe saved, but this one still belongs to the Sunday table, alive and spooned hot.
