Instant Pot Mushroom and Potato Paprikash 

Step 1

Turn on a 6- to 8-quart electric pressure cooker and select the sauté setting (on the more, or hot, setting, if you have it). Add the vegetable oil, then half of the mushrooms. Season with salt, and brown for about 5 minutes, stirring once or twice. Remove the first batch of mushrooms and place on a plate. Add a little more oil if the pot is dry, and brown the second batch the same way, seasoning with salt and transferring the mushrooms to the plate when done.

Step 2

Add the butter to the pot, then the onion. Season with salt and cook for 2 minutes, stirring, until the onion just begins to soften. Add the garlic, and cook for 1 minute more, until the garlic is fragrant. Add the sweet and smoked paprikas; stir well to combine the spices with the onion. Add the wine and carefully scrape up all the browned bits on the bottom of the pot with a spatula. Add the vegetable stock, then the potatoes and mushrooms, along with any accumulated liquid on the plate. Season generously with black pepper. Turn off the sauté setting. Close the lid and twist the pressure knob to seal. Cook on high pressure for 2 minutes.

Step 3

Turn off the pressure cooker and quick-release the pressure by carefully turning the pressure knob to venting. While the steam releases, combine the sour cream with the flour in a medium bowl. Uncover the pot and stir in the crushed tomatoes. Whisk a few ladlefuls of the hot liquid into the sour cream mixture. Add the sour cream mixture and the herbs to the pot. Stir well, and adjust the texture of the stew with up to ½ cup of water if it is too thick for your taste. Taste and add more salt and pepper, if you like.
