Heat three tablespoons schmaltz (or olive oil) in a large pot, and then add diced vegetables to sauté. Add more schmaltz as needed.

Add Blush Chablis and bring to a boil.

Once it reaches a boil, lower flame to a simmer, and add veal roast. Cook for an hour and a half, then remove veal from the sauce and let cool completely.

Once the veal is cooled, slice. Warm up on 250 degrees Fahrenheit for up to a few hours. Finish with freshly grated horseradish.

Using an immersion blender, blend the vegetables to create a creamy, smooth sauce. Use as a gravy or stock for your Pesach cholent or soups. You can also freeze it and use when needed.
