After reviewing it, I use mostly Tony's recipe for corning spices, but with the salt proportion and dry corning method from the other book. Tony calls for yellow mustard seed, Turkish bay leaves, white and black peppercorns, allspice berries, and celery seeds.
The other book uses salt, bay leaves, black pepper, thyme, allspice, and paprika.
I usually use 1/4 cup of salt, plus 1/4+ cup of spice mix for a 4-5 lb brisket.
The spice mix contains (cracked/lightly ground in a coffee/spice mill before using):
1/4 cup mustard seed
5 bay leaves
2 Tbs of peppercorns (I use black, sometimes long pepper, sometimes some Szechuan too)
1 tsp celery seed
1/2 tsp allspice
I rub it with the salt, then the spice, put it in a 2-gallon ziploc in the fridge with bricks on top, flip it daily for 5-10 days. Wash it and rub it with some fresh spice blend (no salt) before cooking.
We like it. The lack of nitrates makes they meat turn brownish grey during cooking, but we don't mind.
