okay! so take a large saucepan and heat over medium low, and melt the butter in it. add the mushrooms and turn the heat up a notch or so and cover, stirring occasionally until the mushrooms give up their liquid. once the pot gets soupy, add the onion and put the lid back on until the mushrooms are brown and the onion is fully cooked through. once this is achieved, remove the lid and cook off most (not all!) of the liquid. at this point, add the flour and paprika TOGETHER, and mix! this will get gluey and start sticking all over the place- that's fine. cook while stirring for a few minutes, enough for the paprika to gain aroma and the flour to darken. next, add the stock and soy sauce, and stir to work all of the clumps of flour off the bottom of the pan and into the liquid. once the soup is smooth, add the milk and bring to a light boil. once the pot boils, lower to the heat to a simmer and ignore for 10 minutes. once the time is up, REMOVE THE PAN FROM THE HEAT and allow to cool slightly. once the pan is no longer scorching hot, add the sour cream and dill, and stir it in. lastly, add the lemon juice and parsley, plus salt and pepper to taste, and stir again to make it all a smooth lovely soup. serve immediately.
