Here's one from allrecipes.com. There are several other ones there.
2 pounds ground beef
2 tablespoons mustard seed
1 tablespoon garlic powder
2 tablespoons liquid smoke flavoring
2 tablespoons sugar-based curing mixture (such as Morton® Tender Quick®)
1 teaspoon coarse ground black pepper
In a large bowl, mix together the ground beef, mustard seed, garlic powder, liquid smoke, curing salt, and pepper using your hands. Form into two equal logs, and wrap each one in aluminum foil with the shiny side facing the meat. Refrigerate for 24 hours.
Preheat the oven to 325 degrees F (165 degrees C). Poke small holes through the aluminum foil in the bottom of the meat rolls using a toothpick. Place on a broiler rack and fill the broiler pan with 1/2 inch of water.
Bake for 90 minutes in the preheated oven. Cool slightly, then refrigerate for 12 hours before unwrapping and serving.
Jason, that cookbook I mentioned will also have a lot of tips and tricks about dealing with the meat mixture and how to cook it. One tip I can give is, if you have a KitchenAid mixer, use that with the dough hook to mix everything with. Do that on a lower setting so you don't burn up the motor.
