Schwammerlcremesuppe

Every autumn in Salzburg, the Grünmarkt fills up with Schwammerl. Wooden crates of Eierschwammerl glowing that impossible egg-yolk gold, Steinpilze with caps the size of your fist, Parasol mushrooms fanning out like little umbrellas. The vendors know their forests the way a fisherman knows his stretch of river. You point, they tell you where it grew and how to cook it.

Gretel always said that a proper Austrian soup tells you the season before you taste it. Schwammerlcremesuppe is autumn in a bowl. You cook the mushrooms hard in butter until they give up their water and start to brown, then you build the soup around them with a light roux, good stock, and enough cream to make the whole thing feel like velvet. The flavor should be deep and earthy, not delicate. This is forest food dressed up just enough for the dining table.

I make this soup at my restaurant from late August through November, when the wild mushrooms are at their peak. Outside of season, I don't make it at all. Good cultivated mushrooms will give you a decent version in winter, and I'll tell you how, but the real thing depends on what the woods provide. If you can get your hands on fresh Eierschwammerl or Steinpilze, even a small handful mixed with ordinary mushrooms, you'll taste the difference in every spoonful.

The technique is not complicated, but two things matter: cook the mushrooms properly and don't drown them in cream. The mushrooms are the voice of this soup. The cream is there to carry them, not to take over.
