Heat up 4 tablespoons of oil in a frying pan and fry six slices of chopped bacon until fragrant and lightly brown, then set aside.
In the same pan fry the the onion and garlic until translucent. Then add the ground pork and ham and fry until it starts to brown.
Mix in the almonds, prunes, apples, celery and 1/2 cup (125 ml) of sweet sherry.
Bring to a boil over low heat until the mixture has reduced a little.
Remove from heat and allow it to cool.
Stuff the turkey with this meat mixture and sow the opening shut using a needle and kitchen thread.
Tie the legs and wings together to prevent them from spreading out during cooking.
Cover the turkey breast with the six slices of bacon. Then cover the baking tray with aluminum foil. Place the turkey in the oven and bake for approximately 5 ½ hours (1 hour/ kilogram, or 30 minutes/ pound).
Baste every 40 minutes with the juice that drips from the turkey and cover again.
Half an hour before it is ready, remove the foil so that the top browns (if it is very dry, pour half a cup of water mixed with half a cup of white wine).
When ready, remove from the heat and leave to rest at room temperature for 20 minutes before serving.
