Pat cutlets dry. Season cutlets with salt and pepper, then dredge in flour, then egg, then bread crumbs. In a large skillet, add clarified butter and saute cutlets on both sides until golden brown and crunchy. Drain on paper towels, keep warm.
In a separate skillet over high heat, cook the bacon and the onions until they both start to brown. Add mustard and capers. Add a small lump of butter to the mix and immediately add the chanterelles. As the mushrooms begin to absorb the butter, add just enough cream to cover the bottom of the pan. Simmer sauce to reduce slightly. Add more mustard or capers, as needed.
To serve, spoon sauce over browned schnitzels.
