Method

Clean the fresh wild mushrooms with a damp brush (avoid soaking them in water, as they act like sponges). Tear or roughly chop them into chunky, bite-sized pieces. Dice the smoked bacon, slice the kiełbasa into rounds, and finely chop the onions and garlic.
Chuck the diced bacon into a cold, heavy-based pan or cast iron skillet and place over a medium heat. Let the fat render out slowly (about 8-10 minutes) until the bacon is crisp and golden.
Tip the sliced sausage into the pan and fry in the bacon fat until the edges are nicely caramelised. Use a slotted spoon to remove the meats to a plate, leaving the liquid gold fat in the pan.
Melt the unsalted butter into the pork fat. Add the onions and sweat for 5 minutes until soft and translucent, then stir in the garlic for a further minute.
Crank up the heat to medium-high and tip in the fresh wild mushrooms. Let them sit for a moment to catch some colour, then stir. They will release a lot of water; keep frying until this moisture completely evaporates and the mushrooms begin to caramelise and squeak in the fat.
Sprinkle the plain flour over the mushrooms and stir constantly for 1 minute to cook out the raw starch.
Pour in the beef stock to deglaze the pan, aggressively scraping up all the sticky, smoky bits from the bottom. Return the cooked bacon and sausage to the pan.
Bring the liquid to a gentle bubble, turn the heat down, and simmer for 5 to 7 minutes until the sauce reduces and heavily coats the back of a spoon. Add half the salt now, bearing in mind the cured meats and stock are already quite salty.
Stir in the double cream and gently simmer for a final 2 minutes. Taste and adjust the seasoning with the remaining salt only if needed, alongside a heavy dose of black pepper. Scatter with freshly chopped parsley just before serving.

Chef's Note & Storage

Fridge for up to 3 days. Reheat gently on the hob over a low heat; do not boil rapidly or the fresh cream may split.

The Heart of the Polish Forest

There is an undeniable magic to Polish woodland foraging, where the earthy scent of wild mushrooms has defined our culinary heritage for generations. Sos grzybowy z boczkiem i kiełbasą is a masterclass in pairing that deep, damp earthiness with the robust, smoky punch of cured pork. By swapping dried fungi for a fresh forest bounty—think ceps, bay boletes, and chanterelles—this sauce takes on a completely different, vibrant texture. It isn't a delicate, fussy jus; it is a proper, rustic sauce built on rendered fat, concentrated mushroom juices, and a rich double cream finish, designed to generously coat placki ziemniaczane, kopytka, or thick ribbons of pasta.

CHEF'S SECRET: Fresh wild mushrooms hold a tremendous amount of water. If you just gently sweat them, they will boil in their own liquid and turn rubbery. You must crank the heat and fry them aggressively in the rendered bacon fat until that moisture completely evaporates. Only then will they begin to caramelise, intensifying their deep, meaty flavour.

Building the Base

Great sauces demand patience at the foundation. Starting the smoked bacon in a cold pan allows the fat to render slowly, crisping the meat without burning it. That resulting fat becomes the cooking medium for the smoked sausage, onions, and the fresh wild mushrooms, embedding every single element with a deeply savoury, smoky profile before the stock, flour, and cream even enter the equation.
