Preparation
Sauté the kidneys over high heat in 10 g butter. As soon as they release their juices, transfer to a colander and rinse thoroughly—this removes their strong flavor.
Return them to the pan with remaining butter for a few minutes, seasoning with salt and pepper.
Sprinkle with flour and brown while stirring, then add the red wine and mustard. Simmer until nearly cooked through.
Add mushrooms shortly before finishing. Sprinkle with parsley and serve with fresh tagliatelle.
