Rahmfisolen

In my grandmother Eva's kitchen in Deal, Rahmfisolen showed up at the table so often I thought it was just how green beans existed. Butter, cream, a splash of vinegar. The sauce clung to the beans in a thin, glossy coat, and I'd eat them off the serving spoon before anyone could stop me. It wasn't until I was older, training at GAFA in Vienna, that I understood what I'd been eating all along: a textbook Einbrenn sauce, the flour-and-butter base that runs through half of Austrian home cooking like a quiet backbone.

The dish is disarmingly simple. You blanch fresh green beans until they're just tender, make a quick cream sauce in the same time it takes to set the table, and toss them together. The whole thing is done in forty minutes. But simplicity is not the same as plainness. The cream sauce gets its character from a shot of white wine vinegar stirred in at the end. That acidity is the secret. It lifts the richness, brightens the beans, and turns something that could have been bland into something you can't stop eating.

Austrians call green beans Fisolen, a word that came north from Italy centuries ago and never left. Rahmfisolen means beans in cream, and it's one of those Beilagen, side dishes, that every Austrian cook learns early because it goes with everything. Roast pork. Tafelspitz. Bread dumplings on a Tuesday. I serve it at my restaurant in Salzburg year-round, though the summer version, when the beans come straight from the Grünmarkt and snap clean between your fingers, is the one that makes me happiest.
