Purchase ground beef in bulk & brown it in the oven

• Press the beef into a large pan with at least 2 inch sides.
• Dissolve 1/4 teaspoon of soda in a bit of water for each pound of beef. This tenderizes the beef.
• Sprinkle the meat with some salt and pepper and the dissolved soda mixture.
• Gently mix the meat to combine the seasonings and baking soda.
• Make deep depressions the meat with fingers to create air pockets so the meat cooks more evenly.
• Bake, covered in foil,  at 350° until the meat reaches 160°.
• Cool in the pan a bit then crumble the meat and drain well.
• Cool to room temperature. Scoop 2 cups of burger (about 10 ounces) into sandwich bags flatten and seal to remove air.
• Store the sandwich bags in a gallon ziplock bag and freeze.
• When ready to use,  break up the meat with a meat pounder.
