To make the pate spice, put all the pate spice ingredients in a small food processor, spice grinder, and grind them until they are a relatively fine powder. Yes, you can do it by hand with a mortar and pestle or a molcajete - if you want strong arms. Put the finished spice in a jar. Store it in a cool, dark place.
Remove any wrapping from the turkey. If there is a bag of giblets, remove that, too. You can give that to the cat.
Crush the peppercorns with a heavy pot to break them up a bit. They do not have to be ground, just crushed a little bit.
To make the brine
Combine all ingredients EXCEPT ice and the last quart of water in a very large bowl that will hold a gallon of liquid.
Stir well.
Transfer to a 4-quart saucepan and bring just to a rolling boil.
Immediately turn off the heat.
Return to the original bowl and add ice and remaining water.
Stir to chill thoroughly.
Place cleaned turkey in a large clean garbage bag. Carefully add brine to the bag, seal, and put in the refrigerator. After 6 hours, turn the bird over and continue to refrigerate until ready to cook.
