Clean and thinly slice the mushrooms. Finely chop the onion and mince the garlic. Dice the bacon or speck.
02 -
In a large skillet over medium heat, cook the diced bacon or speck until golden and crisp. Remove the bacon pieces with a slotted spoon and set aside, retaining the rendered fat in the pan.

Add butter to the hot skillet. When melted, add chopped onion and sauté until translucent. Incorporate minced garlic and 2 sprigs of thyme, cooking briefly. Add the sliced mushrooms and cook, stirring often, until they are golden and moisture has evaporated.

Sprinkle flour over the mushroom mixture and stir thoroughly. Add tomato paste and cook for 2 minutes, stirring constantly to blend.

Gradually pour in the bone broth or stock and Worcestershire sauce, stirring to prevent lumps. Simmer over medium-low heat until the mixture slightly thickens.

In a separate bowl, combine several tablespoons of the hot sauce with the sour cream to warm it gently. Stir this tempered mixture back into the skillet. Avoid boiling to prevent curdling.
07 -
Return the cooked bacon to the skillet. Season with salt and black pepper. Simmer gently until the sauce reaches desired thickness. If the sauce thickens too much, adjust with a splash of water, white wine, or additional stock.
