Eintropfsuppe (Drop Batter Soup)

In my grandmother Eva's kitchen, there were days when the Rindssuppe was already on the stove but nobody had planned the Einlage. No Frittaten waiting in the fridge, no Leberknödel mixture resting. Gretel would look at the pot, look at Eva, and say: Eintropf. Five minutes later, the soup was finished.

Eintropfsuppe is the humblest of Austria's soup garnishes, and I love it for exactly that reason. You whisk together an egg, a few spoonfuls of flour, a little milk, and you drip the batter through a fork into simmering broth. That's the whole recipe. The batter falls in thin streams and sets into delicate, ragged little threads the moment it touches the hot liquid. They float there like golden wisps, tender and light, turning a simple bowl of Rindssuppe into a proper first course.

Austrians have dozens of Einlagen for their clear broth: Frittaten, Leberknödel, Griesnockerl, Backerbsen, and more. Each one makes a different statement about the meal. Eintropfsuppe says: this is a Tuesday. Nobody is showing off. We're just eating well, quickly, together. It's good Austrian home cooking at its most honest, the kind of soup you make when the broth is real and everything else can be simple.

The only thing this recipe asks of you is a good broth. If your Rindssuppe is clear and golden and made from bones simmered with patience, then the Eintropf needs almost nothing to shine. If your broth came from a cube, well. Gretel would have called that phony soup, and no amount of egg batter can fix phony soup.
