Tie the turkey breast at intervals and poach it in a pot with chicken broth until cooked through, about 10 minutes.

Remove, let it cool, and remove the string.

Wrap the turkey breast with the slices of deli ham.

Preheat the oven to 350°F.

In a food processor, combine veal, pork, chicken livers, pork fatback, liver pâté, thyme, nutmeg, salt, and pepper.

Pulse until a medium consistency is achieved.

Gradually add the sherry and egg while pulsing until incorporated.

Line a loaf pan with bacon slices, allowing them to hang over the sides.

Pour half of the pâté mixture into the pan, sprinkle half of the pistachios on top, then place the wrapped turkey breast in the center.

Cover with the remaining pâté mixture and pistachios.

Lay the bay leaves in a row down the center and fold over the bacon slices to cover the pâté completely.

Place the loaf pan in a larger roasting pan.

Carefully pour hot water into the roasting pan to create a water bath around the loaf pan.

Cover the loaf pan tightly with foil.

Bake in the preheated oven for about 1¾ hours.

Remove the pan from the oven, drain any excess fat, and place a weighted object (such as a foil-covered brick) on top of the foil.

Let it cool, then refrigerate for at least 3 days.

Remove the bay leaves and allow the pâté to come to room temperature before serving.

Slice and enjoy!
