3 lb To 3 1/2 lbs boneless veal -shoulder cubed 1 teaspoon salt 5 tablespoons butter 18 peeled white onions water 1 lb fresh mushrooms, quartered 6 2/3 cups chicken stock 2 carrots peeled and cut into -strips 1 teaspoon lemon juice 3 tablespoons flour 1 onion 2 egg yolks 2 celery tops 1 cup heavy cream 1 leek salt 1 teaspoon thyme white pepper 1 bay leaf 2 tablespoons finely chopped parsley 4 parsley sprigs
In a heavy casserole, blanch the veal by covering with cold water, bringing it to a boil over high heat and boiling for one minute. Drain, and rinse under cold water.
Return the veal to the casserole (which has been wiped clean) and add 6 cups of the chicken stock, carrots, onion, celery, leek, herbs and salt. The meat should be covered in liquid; if not, add more water. Bring to a boil and simmer over moderate heat partially covered for 1-1 1/2 hrs until the meat is tender.
Meanwhile, combine 2/3 cups of the chicken stock, 2 tablespoons of butter and the white onions in a skillet. Bring to a boil and simmer 15-20 minutes. Remove with a slotted spoon to a bowel.
Stir the mushrooms and lemon juice to the remaining liquid in skillet. Bring to a boil, cover and simmer for 5 minutes. With a slotted spoon, remove the mushrooms to the bowl with the onions. Pour all remaining liquid into the simmering veal.
When the veal is done, remove from casserole. Strain the stock through a fine sieve, return to casserole and boil until reduced to 1/2.
In a small saucepan, melt 3 tablespoons of butter and stir in flour. Cook this “roux” for 2 minutes and remove from heat. Pour the reduced stock in and blend with a whisk. Then return it to the heat, and cook stirring constantly until the sauce comes to a boil and thickens. Simmer for about 10 minutes. Remove from heat.
In a bowl whisk together egg yolks and cream. Whisk in the hot sauce 2 tablespoons at a time until 1/2 cup has been added. Then reverse the process and whisk the egg-cream-sauce mixture into the hot sauce. (This is to prevent curdling). Bring to a boil in the sauce pan, season with salt and white pepper and a few drops of lemon juice.
Place the veal and vegetables in the large casserole and pour the sauce over. Toss and heat gently. Sprinkle with parsley and serve.
